To investigate the pathogenic variants and function of a pedigree with syndromic hearing loss using high-throughput sequencing. Detailed medical history and pedigree history were inquired, and a pedigree chart was drawn. Hearing examinations were performed on this pedigree, and whole-exome sequencing and bioinformatics analysis were performed to screen for suspected pathogenic variants.

To investigate the clinical and genetic characteristics of nonsyndromic sensorineural hearing loss caused by biallelic variation. A child with hearing impairment who was diagnosed at Gansu Provincial Maternal and Child Health Hospital on May 2022 and was selected as the research object. Peripheral blood of the child and her parents was collected, genomic DNA was extracted.

Objective: The objective of this study was to determine the prevalence and spectrum of genetic mutations linked to inherited breast and ovary cancer (HBOC) in the Indian population, and to evaluate the correlation of BRCA mutation types, frequency, and incidence with age, gender, and personal and family history.
Methods: A retrospective cohort of 500 Indian HBOC patients, meeting NCCN criteria who underwent BRCA1/2 testing from 2017 to 2023 were shortlisted for this study. The anonymized data was retrieved from medical records.

Background: Prenatal whole exome sequencing (WES) is becoming an increasingly used diagnostic tool for fetuses with structural anomalies. However, the identification of variants of uncertain significance (VUS) in clinically relevant genes can significantly complicate prenatal diagnosis and genetic counseling.
Case Presentation: A fetus conceived through in vitro fertilization at the third attempt presented with polydactyly and molar tooth sign at 24 + 6 weeks of gestation.
