Type 3 hereditary hemochromatosis (HH) is a rare form of HH characterized by genetic mutation in the gene. Clinical features reported in patients with type 3 HH include abnormal liver function, liver fibrosis, cirrhosis, diabetes, hypogonadism, cardiomyopathy, and skin pigmentation. Since its original description in 2000, 33 pathogenic mutations associated with HH have been described until now. Here, we first reported a Chinese pedigree of -related hemochromatosis with a novel compound heterozygous mutation c.1288G > A (p.G430R)/c.960T > A (p.Y320X). Interestingly, different phenotypes were reported although the proband and his sister shared the same gene mutation. This inconsistency between genotypes and phenotypes indicates multifactorial etiology contributing to the development of HH. Our report broadens the mutation spectrum of the gene associated with HH.

Objective: To identify the disease-causing variant in a family with tuberous sclerosis complex (TSC).
Methods: This study including a Han-Chinese pedigree recruited from the Third Xiangya Hospital, Central South University, Changsha, Hunan, China was conducted between February, 2019 and January, 2023. Detailed clinical examinations were performed on the proband and other family members of a Han-Chinese family with TSC.

Objective: To analyze gene mutation found in a pedigree with clinical features and inheritable pattern consistent with amelogenesis imperfecta (AI) in China, and to study the relationship between its genotype and phenotype.
Methods: Clinical and radiological features were recorded for the affected individuals. Peripheral venous blood samples of the patient and family members were collected for further study, and the genomic DNA was extracted to identify the pathogenic gene.

In this study, patients with inherited retinal dystrophies (IRDs) who visited Ningxia Eye Hospital from January 2015 to September 2023 were analyzed. Through Whole Exome Sequencing (WES) and Sanger verification, 17 probands carrying homozygous variants were detected. The association between the genotype and clinical phenotype of patients with homozygous variants was analyzed.

Background: Glycerol-3-phosphate dehydrogenase 1 (GPD1) gene defect can cause hypertriglyceridemia (HTG), which usually occurs in infants. The gene defect has rarely been reported in adult HTG patients. In the present study, we described the clinical and functional analyses of a novel GPD1 missense variant in a Chinese adult patient with recurrent hypertriglyceridemia‑related acute pancreatitis (HTG-AP), consuming a high-fat diet and smoking heavily.
