Objective:To explore the clinical characteristics and genetic variants of two children with 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency (HMGCLD).Methods:Two children with HMGCLD diagnosed at Henan Provincial Children′s Hospital respectively in December 2019 and June 2022 were selected as the study subjects. Clinical data and results of laboratory testing were analyzed retrospectively.Results:Both children had manifested with repeated convulsions, severe hypoglycemia, metabolic acidosis and liver dysfunction. Blood amino acids and acylcarnitine analysis showed increased 3-hydroxy-isovalyl carnitine (C5OH) and 3-hydroxy-isovalyl carnitine/capryloyl carnitine ratio (C5OH/C8), and urinary organic acid analysis showed increased 3-hydroxyl-3-methyl glutaric acid, 3-methyl glutaric acid, 3-methyl glutacoic acid, 3-hydroxyisoglycine and 3-methylprotarylglycine. Child 1 was found to harbor homozygous c. 722C>T variants of the HMGCL gene, which was rated as uncertain significance(PM2_Supporting+ PP3). Child 2 was found to harbor homozygous c. 121C>T variants of the HMGCL gene, which was rated as pathogenic(PVS1+ PM2_Supporting+ PP4). Conclusion:Acute episode of HMGCLD is usually characterized by metabolic disorders such as hypoglycemia and metabolic acidosis, and elevated organic acids in urine may can facilitate the differential diagnosis, though definite diagnosis will rely on genetic testing.

Objective:To explore the clinical features and genetic variants in three children suspected for β-ketothiolase deficiency (BKTD).Methods:Clinical manifestations, laboratory examination and genetic testing of three children suspected for BKTD at Henan Children′s Hospital between January 2018 and October 2022 were collected, and their clinical and genetic variants were retrospectively analyzed.Results:The children were all males with a age from 7 to 11 months. Their clinical manifestations have included poor spirit, shortness of breath, vomiting, convulsions after traumatic stress and/or infection. All of them had severe metabolic acidosis, elevated ketone bodies in blood and urine, hypoglycemia, with increased isoprenyl-carnitine and 3-hydroxyisovalyl-carnitine in the blood, and 2-methyl-3-hydroxybutyrate and methylprotaroyl glycine in the urine. All of them were found to harbor compound heterozygous variants of the ACAT1 gene, including c. 1183G>T and a large fragment deletion (11q22.3-11q23.1) in child 1, c. 121-3C>G and c. 826+ 5_826+ 9delGTGTT in child 2, and c. 928G>C and c. 1142T>C in child 3. The variants harbored by children 2 and 3 were known to be pathogenic or likely pathogenic. The heterozygous c. 1183G>T variant in child 1 was unreported previously and rated as a variant of unknown significance (PM2_Supporting+ PP3+ PP4) based on guidelines from the American College of Medical Genetics and Genomics. The large segment deletion in 11q22.3-11q23.1 has not been included in the DGV Database and was rated as a pathogenic copy number variation. Conclusion:The variants of the ACAT1 gene probably underlay the pathogenesis of BKTD in these three children.

Objective:To explore the clinical phenotype and genetic characteristics of a Chinese pedigree affected with Spastic paraplegia type 5A (SPG5A).Methods:A pedigree suspected for Hereditary spastic paraplegia (HSP) at Henan Children′s Hospital on August 15 2022 was selected as the study subject. Clinical data of the pedigree was collected. Peripheral blood samples were collected from members of the pedigree. Following extraction of genomic DNA, trio-WGS was carried out, and candidate variant was verified by Sanger sequencing.Results:The child, a 1-year-old boy, had presented with microcephaly, hairy face and dorsal side of distal extremities and trunk, intellectual and motor development delay, increased muscle tone of lower limbs, hyperreflexes of bilateral knee tendons, and positive pathological signs. His parents and sister both had normal phenotypes. Trio-WGS revealed that the child has harbored a homozygous c. 1250G>A (p.Arg417His) variant of the CYP7B1 gene, for which his mother was heterozygous, the father and sister were of the wild type. The variant was determined to have originated from maternal uniparental disomy (UPD). The result of Sanger sequencing was in keeping with the that of trio-WGS. SPG5A due to maternal UPD of chromosome 8 was unreported previously. Conclusion:The child was diagnosed with SPG5A, a complex type of HSP, for which the homozygous c. 1250G>A variant of the CYP7B1 gene derived from maternal UPD may be accountable.

Objective:To explore the clinical characteristics and genetic variants in three children with late-onset Multiple acyl-Coenzyme A dehydrogenase deficiency (MADD type Ⅲ).Methods:Clinical data of three children diagnosed with late-onset MADD at the Children′s Hospital Affiliated to Zhengzhou University between March 2020 and March 2022 were retrospectively analyzed. All children were subjected to whole exome sequencing (WES), and candidate variants were verified by Sanger sequencing. All children had received improved metabolic therapy and followed up for 1 ~ 3 years.Results:The children had included 2 males and 1 female, and aged from 2 months to 11 years and 7 months. Child 1 had intermittent vomiting, child 2 had weakness in lower limbs, while child 3 had no symptom except abnormal neonatal screening. Tandem mass spectrometry of the three children showed elevation of multiple acylcarnitines with short, medium and long chains. Children 1 and 2 showed increased glutaric acid and multiple dicarboxylic acids by urine Gas chromatography-mass spectrometry (GC-MS) analysis. All children were found to harbor compound heterozygous variants of the ETFDH gene, including a paternal c. 1211T>C (p.M404T) and a maternal c. 488-22T>G variant in child 1, a paternal c. 1717C>T (p.Q573X) and a maternal c. 250G>A (p.A84T) variant in child 2, and a paternal c. 1285+ 1G>A and maternal c. 629A>G (p.S210N) variant in child 3. As for the treatment, high-dose vitamin B2, levocarnitine and coenzyme Q 10 were given to improve the metabolism, in addition with a low fat, hypoproteinic and high carbohydrate diet. All children showed a stable condition with normal growth and development during the follow-up. Conclusion:The compound heterozygous variants of the ETFDH gene probably underlay the muscle weakness, remittent vomiting, elevated short, medium, and long chain acylcarnitine, as well as elevated glutaric acid and various dicarboxylic acids in the three children with type Ⅲ MADD.

Objective:To construct and validate a machine learning model for preoperative prediction of perineural invasion (PNI) status in intrahepatic cholangiocarcinoma (ICC).Methods:Clincial data of 329 patients, including 245 admitted to Zhengzhou University People's Hospital from January 2018 to June 2023 and 84 admitted to the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to January 2020 were retrospectively analyzed. Patients were divided into a training set ( n=231) and a validation set ( n=98). Clinicopathological data including age, gender, hepatitis B virus (HBV) infection status were collected. Predictive variables were determined using least absolute shrinkage and selection operator (LASSO) regression analysis. Six machine learning algorithms including random forest (RF), logistic regression, and linear kernel-based support vector machine were selected to construct the preoperative prediction model for PNI in ICC. Performance metrics of the model were calculated using a confusion matrix, and the final model was selected. The model performance was evaluated in the validation set. Calibration curves were plotted to evaluate the final model, and a Pareto chart was used to visualize the importance of predictive variables. Results:LASSO regression identified nine predictive variables included in the prediction model, including carbohydrate antigen 19-9 (CA19-9), HBV infection status, alkaline phosphatase, alanine aminotransferase, prothrombin time, total bilirubin, albumin, neutrophil times gamma-glutamyl transferase to lymphocyte ratio, and tumor burden score. Among the trained six models, the area under the curve (AUC) of the RF model was 0.909, with a sensitivity of 0.842 and an accuracy of 0.870. Compared with the AUC of the RF model, the AUCs of the other 5 models were lower (all P<0.05). The AUC of the RF model for predicting PNI in ICC in validation set was 0.736. Calibration curves showed good fit of the RF model's prediction of PNI in ICC in both training and validation sets. The Pareto chart showed that CA19-9 was the most important predictive variable in the model, followed by HBV infection status. Conclusion:The machine learning model based on the RF algorithm has a high accuracy in preoperative prediction of PNI status in ICC.

Objective:To analyze the effect of sarcopenia on the prognosis of patients with hepatocellular carcinoma (HCC) after laparoscopic radical resection.Methods:Clinical data of 165 patients with HCC undergoing laparoscopic radical resection in Henan University People's Hospital from January 2018 to December 2021 were retrospectively analyzed, including 122 males and 43 females, aged (55.5±11.4) years. Patients were divided into sarcopenia group ( n=79) and control group (non-sarcopenia, n=86) according to the skeletal muscle index. The survivals were analyzed using the Kaplan-Meier method, and were compared by the log-rank test. Univariate and multivariate Cox regression were utilized to analyze the effect of sarcopenia on the prognosis of HCC after laparoscopic radical surgery. Results:The 1- and 3-year cumulative survival rates of control group were 96.4% and 81.2%, which were higher than those of the sarcopenia group (83.2% and 48.9%, respectively, χ2=19.67, P<0.001). The 1- and 3-year recurrence-free survival (RFS) rates of control group were 88.4% and 66.1%, which were higher than those of sarcopenia group (70.9% and 37.7%, respectively, χ2=18.80, P<0.001). Multivariate Cox regression analysis showed that the risk of recurrence ( HR=1.35, 95% CI: 1.20-1.59, P<0.001) and the risk of death ( HR=2.21, 95% CI: 1.23-3.41, P=0.001) after laparoscopic radical resection for HCC in patients with sarcopenia rises compared to non-sarcopenic patients. Conclusion:Sarcopenia is a risk factor for the survival and recurrence of HCC after laparoscopic radical surgery.

Objective:To investigate the clinical and genetic features of patients with spastic paraplegia and psychomotor retardation with or without seizures (SPPRS) caused by HACE1 gene mutation. Methods:Clinical data, auxiliary examination and genetic test results of a child with SPPRS caused by HACE1 gene mutation who was admitted to Henan Children′s Hospital in April 2019 were collected. The clinical and genotypic characteristics of children with SPPRS were summarized by searching the relevant literature up to June 2024, retrieved from CNKI, Wanfang and PubMed databases with the terms of " HACE1" "SPPRS" "seizures" "spastic paraplegia". Results:The patient was a 11 months and 20 days old male, with a clinical phenotype including global developmental delay, leg spastic tremor, frequent epileptic seizures, obesity, and concurrent urethral malformation. Brain magnetic resonance imaging (MRI) showed enlarged bilateral ventricles, hypoplastic corpus callosum, delayed myelination. Genetic test results revealed compound heterozygous variants c.994C>T (p.R332 *) and c.1679-2A>G in the HACE1 gene (according to the transcript NM_020771), respectively inherited from his mother and father, with c.1679-2A>G being a newly reported variant. A total of 6 English literatures reported 21 SPPRS patients in 11 families, and HACE1 gene mutations were mainly characterized by nonsense mutations. The main clinical manifestations included global developmental delay (21 cases), movement disorders (21 cases), intellectual disabilities (18 cases), seizures (13 cases), obesity (13 cases), skeletal abnormalities (11 cases), microcephaly (9 cases), ocular abnormalities (9 cases), distinctive facial features (5 cases), sensorineural hearing loss (5 cases), and short stature (3 cases). MRI predominantly showed hypoplasia of the corpus callosum, ventricular dilation, paucity of white matter and cerebral atrophy. There were no clear genotype-phenotype correlations. A total of 13 HACE1 gene mutations were reported, including 9 nonsense mutations, 2 frameshift mutations, 1 in-frame mutation, and 1 missense mutation. Among the 11 families, only 2 families with 5 patients were caused by compound heterozygous mutations, c.1852_1853del (p.L832del) and c.454C>T (p.Q152 *), c.2242C>T (p.R748 *) and c.2019_2020insTTTAGGTATTTTTAGGTATT (p.P674fs). The other 16 patients in 9 families were caused by homozygous mutations of the remaining 9 mutations. Conclusions:SPPRS is rare and usually occurs in infancy. The main clinical manifestations include comprehensive developmental delay, movement disorders, epilepsy, etc. Currently, no clear genotype-phenotype correlation has been found. The c.1679-2A>G variant of the HACE1 gene is an unreported variant and enriches the mutation spectrum of the HACE1 gene.
