A groundbreaking study involving nearly 30,000 families has revealed that most undiagnosed developmental disorders linked to recessive genes are associated with known genes, SciTech Daily reported yesterday.<\/p>\n\n\n\n
Conducted by researchers from the Wellcome Sanger Institute and GeneDx, this research analyzed genetic data from a diverse cohort, including over 20% from non-European ancestries.<\/p>\n\n\n\n
The findings, published in Nature Genetics, indicate that known genes account for approximately 84% of cases caused by recessive variants, a significant increase from earlier estimates. Researchers identified new genes, such as KBTBD2 and CRELD1, associated with these disorders, providing insights for previously undiagnosed families.<\/p>\n\n\n\n
The study highlights the role of consanguinity in varying prevalence rates across different ethnic groups, ranging from 2% to 19%. Researchers emphasize the need for improved interpretation of genetic changes in known genes to enhance diagnosis rates, potentially doubling the number of patients diagnosed without additional samples.<\/p>\n","protected":false},"excerpt":{"rendered":"
