OBJECTIVES

This study aimed to describe the demographic profile, intervention sessions, goal attainment scaling (GAS), and health-related quality of life (HRQOL) of autistic children receiving speech and language therapy (SLT) in a higher educational institution in the Philippines.

Deidentified data from 18 autistic children aged 4–16 years (mean=8.2; SD=2.9) who received SLT for two months were analyzed. Their demographic profile, intervention sessions, GAS scores, and generic HRQOL scores were documented.

Most participants were school-age children (n=12; 66%) and were boys (n=14; 78%). After two months, the GAS scores of 11 participants (61%) increased by 1–2 points, whereas the scores of the remaining participants decreased (n=6; 33%) or did not change (n=1; 6%). Their mean generic HRQOL scores before and after SLT were 65.6 (SD=15.2) and 61.2 (SD=17.4), respectively.

While the GAS scores increased for most participants, their generic HRQOL scores did not show clinically significant changes after two months of SLT. This can be attributed to the few therapy sessions and short follow-up period. The findings highlight the need to provide long-term support to SLT services of autistic children in the Philippines to document more desirable quality of life outcomes.

OBJECTIVE: To explore the clinical characteristics and genetic etiology for two children with Neurodevelopmental disorder with hypotonia, stereotypic hand movements, and impaired language (MEDHSIL). METHODS: Two children who had visited the Ningbo Women and Children's Hospital on October 15, 2021 were selected as the study subjects. Whole exome sequencing (WES) was carried out for both patients. Candidate variants were verified by Sanger sequencing of their family members. RESULTS: The two children were respectively found to harbor a heterozygous c.138delC (p.Ile47Serfs*42) variant and a c.833del (p.L278*) variant of the MEF2C gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PVS1+PS2+PM2_Supporting). CONCLUSION The c.138delC and c.833del variants of the MEF2C gene probably underlay the pathogenesis of MEDHSIL in the two children. Above findings have enriched the mutational spectrum of the MEF2C gene and enabled genetic counseling for their families.

OBJECTIVE: To explore the clinical and genetic characteristics of a boy with isolated maternal uniparental disomy of chromosome 20 [UPD(20)mat]. METHODS: A child who was admitted to the Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology on April 8,2021. was selected as the study subject. Phenotypic and endocrinological findings of the child were retrospectively analyzed. Whole exome sequencing (WES) and methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) were carried out for detecting the UPD sequences and copy number variations. Both of his parents were verified by Sanger sequencing. Relevant literature was systematically reviewed. RESULTS: The child, a 3-year-and-8-month-old boy born to a 41-year-old mother by Cesarean delivery at 36⁺² gestational weeks due to oligohydramia, had a birth weight of 2 300 g and length of 46 cm. He was admitted to the NICU for feeding difficulties which had persisted despite of clinical management. At the age of 3.75, he had a height of 92.5 cm (< 3rd percentile; 25th ~ 50th percentile at 2.5 years) and a weight of 10.8 kg (< 3rd percentile; 50th percentile at 15 months). He had also presented with growth retardation, short stature, attention deficit and hyperactivity disorder (ADHD), mild mental retardation, and speech and language development disorders. He had simian creases in both hands but no additional dysmorphic signs, and his motor development was normal. Serum insulin, thyroid-stimulating hormone, and insulin growth factor binding protein 3 levels were within the normal ranges, though insulin growth factor-1 (IGF-1) was slightly decreased. Since that time he had continuously used atomoxetine hydrochloride capsules to control his ADHD. WES and MS-MLPA revealed the existence of UPD (20)mat. CONCLUSION The UPD(20)mat syndrome is characterized by feeding difficulties, growth retardation and short stature. The child in our case has been accompanied by ADHD and speech and language development disorders, which required long-term treatment. For women with advanced maternal age and suggestive phenotypes, genetic testing and counseling should be conducted.

OBJECTIVE: To analyze the clinical features and genetic variants in two unrelated patients with psychomotor retardation and facial abnormalities, and to explore their genotype-phenotype correlation. METHODS: Clinical data and family history of the two pedigrees were collected. Whole exome sequencing (WES) and Sanger sequencing were carried out to detect the potential variants. RESULTS: Both patients had presented with mental and language retardation, along with growth delay and facial anomalies. They were both found to harbor de novo loss-of-function variants in exon 12 of the ASXL3 gene, namely c.3096dup (p.Pro1033Thrfs*2) and c.3253G>T (p.Gly1085*). Neither variant was reported previously. Combined with their clinical features and genetic finding, both patients were diagnosed with Bainbridge-Ropes syndrome due to pathogenic variants of the ASXL3 gene. CONCLUSION Diagnosis of Bainbridge Ropes syndrome in the two pedigrees has enriched the genotypic and phenotypic spectrum of this disorder and enabled genetic counseling for them.

OBJECTIVE: To explore the genetic etiology for a child featuring mental retardation and speech delay. METHODS: Clinical data of the child was collected. DNA was extracted from peripheral blood samples of the child and members of his pedigree. Whole exome sequencing was carried out for the child, and candidate variants were verified by Sanger sequencing. Prenatal diagnosis was provided for his mother upon her subsequent pregnancy. RESULTS: The child has mainly featured mental retardation, speech delay, ptosis, strabismus, photophobia, hyperactivity, and irritability. Whole exome sequencing revealed that he has harbored a pathogenic heterozygous variant of the KAT6A gene, namely c.5314dupA (p.Ser1772fs*20), which was not detected in either of his parents. The child was diagnosed with Arboleda-Tham syndrome. The child was also found to harbor a hemizygous c.56T>G (p.Leu19Trp) variant of the AIFM1 gene, for which his mother was heterozygous and his phenotypically normal maternal grandfather was hemizygous. Pathogenicity was excluded. Prenatal diagnosis has excluded the c.5314dupA variant of the KAT6A gene in the fetus. CONCLUSION The heterozygous c.5314dupA (p.Ser1772fs*20) variant of the KAT6A gene probably underlay the Arboleda-Tham syndrome in this child. Above finding has enabled genetic counseling and prenatal diagnosis for this pedigree.

OBJECTIVE: To analyze the clinical features and genetic basis of three children with mental retardation, language impairment and autistic features due to de novo variants of FOXP1 gene. METHODS: Clinical data of the children were collected.Trio-whole exome sequencing was carried out for the children and their parents. Pathogenicity of the variants was analyzed through bioinformatics prediction. RESULTS: All of the children had various degrees of mental retardation in conjunct with language deficit, global developmental delay, abnormal behavior and peculiar facial features, among whom two also developed autism spectrum disorders. The results of genetic testing showed that all three children harbored de novo variants of the FOXP1 gene, namely c.613_c.614delCTinsTA, c.1248delC and c.1393A>G. Two of these were frameshift variants and one was missense variant, which were all rated as pathogenic based on the guidelines of the American College of Medical Genetics (ACMG). Database search suggested that c.613_c.614delCTinsTA and c.1248delC were unreported previously. CONCLUSION For the three children from unrelated families with mental retardation in conjunct with language deficit, global growth delay, abnormal behavior and peculiar facial features, the c.613_ c. 614delCTinsTA, c.1248delC and c.1393A>G variants of the FOXP1 gene may be the pathogenic factors. Above cases have further expanded the genotype-phenotype profile of FOXP1 deficiency syndrome.

OBJECTIVE: To investigate if therapeutic horseback riding (THR) can improve language and cognitive function in children with autism spectrum disorder (ASD) or intellectual disability (ID). METHODS: We conducted a prospective case-control study on children diagnosed with ASD or ID. Eighteen and 11 children were enrolled for THR and control groups, respectively. For 8 weeks, those in the THR group underwent conventional therapy plus 30 minutes of THR per week while controls only received conventional therapy. Participants’ language (using Receptive and Expressive Vocabulary Test [REVT] and Preschool Receptive-Expressive Language Scale [PRES]) and cognitive abilities (using Kaufman Assessment Battery for Children [K-ABC] and the cognitive domain of Bayley Scales of Infant Development-II [BSID-II]) were assessed at baseline and at 8 weeks after treatment. RESULTS: There was no baseline difference between the two groups. In the THR group, there were statistically significant improvements in most domains after THR including receptive and expressive language and cognition compared to those before THR. In the control group, however, only receptive vocabulary ability assessed by REVT and cognitive function assessed by BSID-II showed improvements after conventional therapy. However, there were no statistically significant differences in language or cognitive abilities between the two groups at 8 weeks after treatment. CONCLUSION: These results suggest that THR might improve language and cognitive abilities. Although the mechanisms and pathways involved in such improvements are currently unclear based on our findings, THR might have potential to optimize language and cognitive abilities of children with ASD and ID.

OBJECTIVE: To evaluate correlations between values of articulation tests and language tests for children with articulation disorder in Korea. METHODS: Data of outpatients with chief complaint of an articulation problem were retrospectively collected. Patients who underwent Urimal Test of Articulation and Phonation (U-TAP) with Assessment of Phonology and Articulation for Children (APAC), Preschool Receptive-Expressive Language Scale (PRES), or Receptive and Expressive Vocabulary Test (REVT) simultaneously were identified. Patients whose word-level percentages of correct consonants in U-TAP (UTAP_wC) were more than 2 standard deviations below the mean as diagnostic criteria for articulation disorder were selected. Those whose receptive language age (P_RLA), expressive language age (P_ELA), or combined language age (P_CLA) in PRES was delayed more than 24 months compared to their chronological age in months as diagnostic criteria for language disorder were excluded. RESULTS: Thirty-three children aged 3–6 years were enrolled retrospectively. PRES and U-TAP showed significant correlations for most of value relationships. PRES and APAC showed significant correlations for all value relationships except for receptive language age. All values of REVT were significantly correlated with all values from U-TAP, but not with any value from APAC. Articulation tests U-TAP and APAC showed significant correlations between percentages of correct consonants. Language tests PRES and REVT showed significant correlations for all value relationships. CONCLUSION: This study suggests that articulation abilities and language abilities might be correlated in children with articulation disorder.

BACKGROUND AND PURPOSE: Benign epilepsy with centrotemporal spikes (BECTS) is one of the most common pediatric epilepsies, and it generally has a good prognosis. However, recent research has indicated that the epileptic activity of BECTS can cause cognitive defects such as language, visuospatial, and auditory verbal memory deficits. This study assessed language-delivery deficits in BECTS patients using diffusion-tensor magnetic resonance imaging (DTI). METHODS: T1-weighted MRI, DTI, and language tests were conducted in 16 BECTS patients and 16 age-matched controls. DTI data were analyzed using the TRActs Constrained by Underlying Anatomy tool in FreeSurfer 5.3, and 18 major white-matter tracts were extracted, which included 4 language-related tracts: the inferior longitudinal fasciculus, superior longitudinal fasciculus-parietal terminations, superior longitudinal fasciculus-temporal terminations, and uncinate fasciculus (UNC). Language tests included the Korean version of the Receptive and Expressive Vocabulary Test, Test of Problem-Solving Abilities (TOPS), and the mean length of utterance in words. RESULTS: The BECTS group exhibited decreased mean fractional anisotropy and increased mean radial diffusivity, with significant differences in both the superior longitudinal fasciculus and the left UNC (p<0.05), which are the language-related white-matter tracts in the dual-loop model. The TOPS language test scores were significantly lower in the BECTS group than in the control group (p<0.05). CONCLUSIONS: It appears that BECTS patients can exhibit language deficits. Seizure activities of BECTS could alter DTI scalar values in the language-related white-matter tracts.
