Muenke syndrome is an autosomal dominant genetic disorder that is typically characterized by unilateral or bilateral coronal synostosis, macrocephaly, midface hypoplasia, and developmental delays. This article reports a case of Muenke syndrome with a soft cleft palate. A heterozygous missense mutation c.749C>G (p.P250A) was identified in the FGFR3 gene through genetic testing. The patient exhibited typical features including coronal synostosis, bilateral hearing loss, right accessory auricle, and developmental delays and underwent surgery to repair the soft cleft palate. Cases of Muenke syndrome with cleft palate in the literature are relatively rare, and common associated symptoms include coronal suture craniosynostosis and hearing impairment. This article reports a differential diagnosis with other craniosynostosis syndromes and provides a reference for clinical diagnosis and treatment.

2.Multiple bone metastases in an elderly Filipino with basal cell nevus syndrome.
Journal of the Philippine Medical Association 2025;104(1):37-41
Basal Cell Nevus Syndrome (BCNS) is a rare autosomal dominant disorder characterized by a range of abnormalities, most notably multiple basal cell carcinomas (BCCs), odontogenic keratocysts, and palmar and/or plantar pits. BCC is the most common form of skin cancer globally. It is typically locally invasive and very rarely metastasizes, with distal metastases occurring in only 0.00028% to 0.55% of cases.
We present a case of a 68-year-old Filipino woman who was diagnosed with BCNS. She presented with multiple black nodules and plaques on her face and neck, histopathologically confirmed as BCCs. In addition, the presence of palmoplantar pits and calcification of the falx cerebri met three of the six major criteria for BCNS. Computed tomography (CT) and bone scans, revealed multiple bone metastases in the cranium, spine, sternum, and ribs. No previous cases of metastasis in a BCNS patient have been reported in the Philippines, making this the first documented case.

Basal cell nevus syndrome is a rare
autosomal dominant disorder with a prevalence
of between 1in 60,000 to 1in 120,000. This disorder is
associated with a panoply of phenotypic
that includes developmental
anomalies and tumors particularly basal cell
carcinoma. The genetic abnormality in almost all
known cases is a mutation in the PATCHED] gene
which is essential for normal body and limb
patterning.?
abnormalities
We report a 50-year-old Filipina who
suffered from multiple recurrent pigmented
papules, plagues, nodules, and tumors on the face
with the first tumor appearing at age 20.

Objective:By analyzing the clinical phenotypic characteristics and gene sequences of two patients with Treacher Collins syndrome(TCS), the biological causes of the disease were determined. Then discuss the therapeutic effect of hearing intervention after bone bridge implantation. Methods:All clinical data of the two family members were collected, and the patients signed the informed consent. The peripheral blood of the proband and family members was extracted, DNA was extracted for whole exome sequencing, and Sanger sequencing was performed on the family members for the mutation site.TCOF1genetic mutations analysis was performed on the paitents. Then, the hearing threshold and speech recognition rate of family 2 proband were evaluated and compared under the sound field between bare ear and wearing bone bridge. Results:In the two pedigrees, the probands of both families presented with auricle deformity, zygomatic and mandibular hypoplasia, micrognathia, hypotropia of the eye fissure, and hypoplasia of the medial eyelashes. The proband of Family 1 also presents with specific features including right-sided narrow anterior nasal aperture and dental hypoplasia, which were consistent with the clinical diagnosis of Treacher Collins syndrome. Genetic testing was conducted on both families, and two heterozygous mutations were identified in the TCOF1 gene: c. 1350_1351dupGG(p. A451Gfs*43) and c. 4362_4366del(p. K1457Efs*12), resulting in frameshift mutations in the amino acid sequence. Sanger sequencing validation of the TCOF1 gene in the parents of the proband in Family 1 did not detect any mutations. Proband 1 TCOF1 c. 1350_1351dupGG heterozygous variants have not been reported previously. The postoperative monosyllabic speech recognition rate of family 2 proband was 76%, the Categories of Auditory Performance(CAP) score was 6, and the Speech Intelligibility Rating(SIR) score was 4. Assessment using the Meaningful Auditory Integration Scale(MAIS) showed notable improvement in the patient's auditory perception, comprehension, and usage of hearing aids. Evaluation using the Glasgow Children's Benefit Inventory and quality of life assessment revealed significant improvements in the child's self care abilities, daily living and learning, social interactions, and psychological well being, as perceived by the parents. Conclusion:This study has elucidated the biological cause of Treacher Collins syndrome, enriched the spectrum of TCOF1 gene mutations in the Chinese population, and demonstrated that bone bridge implantation can improve the auditory and speech recognition rates in TCS patients.

OBJECTIVE:
To preliminarily verify the effectiveness of self-designed artificial condyle-mandibular distraction (AC-MD) complex in the treatment of Pruzansky type ⅡB and Ⅲ hemifacial microsomia (HFM) through model test.
METHODS:
Five children with Pruzansky type ⅡB and Ⅲ HFM who were treated with mandibular distraction osteogenesis (MDO) between December 2016 and December 2021 were selected as the subjects. There were 3 boys and 2 girls wih an average age of 8.4 years (range, 6-10 years). Virtual surgery and model test of AC-MD complex were performed according to preoperative skull CT of children. The model was obtained by three-dimensional (3D) printing according to the children's CT data at a ratio of 1∶1. The occlusal guide plate was designed and 3D printed according to the children's toothpaste model. The results of the model test and the virtual surgery were matched in three dimensions to calculate the error of the residual condyle on the affected side, and the model test was matched with the actual skull CT after MDO to measure and compare the inclination rotation of the mandible, the distance between the condylar of the healthy side and the residual condyle of the affected side, and the lengthening length of the mandible.
RESULTS:
The error of residual condyle was (1.07±0.78) mm. The inclination rotation of the mandible, the distance between the condylar of the healthy side and the residual condyle of the affected side, and the lengthening length of the mandible after 3D printing model test were significantly larger than those after MDO ( P<0.05).
CONCLUSION
In the model test, the implantation of AC-MD complex can immediately rotate the mandible to the horizontal position and improve facial symmetry, and the residual condyle segment can be guided close to the articular fossa or the preset pseudoarticular position of the skull base after operation.

Chinese Journal of Medical Genetics 2023;40(8):1009-1014
OBJECTIVE:
To analyze the clinical and genetic characteristics of an infant with craniosynostosis.
METHODS:
An infant who was admitted to Wuhan Children's Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology in April 2021 due to widening of the lateral ventricles for over a month was selected as the study subject. Clinical data of the patient was collected. Peripheral blood samples were collected from the infant and her parents for chromosomal karyotyping and whole exome sequencing. Candidate variant was verified by Sanger sequencing and bioinformatic analysis. Relevant literature was retrieved from the PubMed, Wanfang and CNKI databases (up to December 2021) by using key words including ERF gene, craniosynostosis, ERF mutation, craniosynostosis and ERF-related craniosynostosis.
RESULTS:
The infant, a 1-month-and-16-day-old female, was found to have sagittal synostosis by cranial X-ray radiography. Genetic testing revealed that she has harbored a heterozygous c.787C>T (p.Q263*) variant of the ERF gene, which was not found in either parent. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was predicted as pathogenic (PVS1+PS2+PM2_Supporting). In total 63 relevant cases were retrieved from the database, and a total of 64 individuals were analyzed by genetic testing. Most of the cases were sporadic and males. Multiple cranial sutures (including at least two of the sagittal suture, coronal suture, lambdoid suture, and frontal suture) were involved in 45.45% of the cases, and those with sagittal suture closure only have accounted for 20.00%. The main clinical manifestations have included hypertelorism, exophthalmos, development delay, malar dysplasia, etc. Chiari type 1 malformation may present in some patients. Variants of the ERF gene have mainly included splicing and deletional variants, and there was a strong genetic heterogeneity among the infants and their pedigrees.
CONCLUSION
The c.787C>T (p.Q263*) variant of the ERF gene probably underlay the craniosynostosis of this infant. Above finding has enriched the phenotype ~ genotype spectrum of the ERF gene.

OBJECTIVE:
To explore the clinical and genetic characteristics of three children with KBG syndrome.
METHODS:
Clinical data of the three children from two families who have presented at the First Affiliated Hospital of Zhengzhou University between October 2019 and September 2020 and their family members were collected. Trio-whole exome sequencing (trio-WES) and Sanger sequencing were carried out.
RESULTS:
All children had feeding difficulties, congenital heart defects and facial dysmorphism. The sib- pair from family 1 was found to harbor a novel de novo heterozygous c.6270delT (p.Q2091Rfs*84) variant of the ANKRD11 gene, whilst the child from family 2 was found to harbor a novel heterozygous c.6858delC (p.D2286Efs*51) variant of the ANKRD11 gene, which was inherited from his mother who had a mild clinical phenotype.
CONCLUSION
The heterozygous frameshift variants of the ANKRD11 gene probably underlay the disease in the three children. Above findings have enriched the spectrum of the ANKRD11 gene variants.
