Sex-determining Region Y
Full Form of SRY
What is SRY?
The SRY gene, short for Sex-determining Region Y, is a critical genetic sequence located on the short arm of the Y chromosome in humans and most other mammals. It plays a pivotal role in male sex determination by encoding a transcription factor known as the testis-determining factor, which triggers the development of testes in the early embryo. Without a functional SRY gene, an XY embryo typically develops along female anatomical pathways, often leading to conditions such as Swyer syndrome. In India, SRY is a key topic in higher secondary biology curricula and is extensively covered in competitive medical entrance examinations like NEET, AIIMS, and JIPMER. The gene was identified in 1990 and remains central to research in reproductive biology, gender determination studies, and forensic DNA profiling. Indian research institutions, including the Indian Institute of Science, the National Institute of Mental Health and Neurosciences, and various CSIR laboratories, actively investigate SRY-related disorders and chromosomal abnormalities. Understanding this gene also helps medical professionals diagnose disorders of sexual development, and it is essential knowledge for fields such as clinical genetics, obstetrics, paediatrics, and molecular biology research across India's rapidly growing biotechnology and pharmaceutical sectors.

Example
Mutations in the SRY gene on the Y chromosome can cause Swyer syndrome, where genetically male individuals develop female characteristics, a topic frequently asked in NEET biology papers.
