BRCA1 Gene
150,000 - 160,000 bp
BRCA1 (BReast Cancer Type 1) is a tumor suppressor gene that plays a crucial role in DNA repair and genomic stability. Mutations in BRCA1 are associated with increased risk of breast and ovarian cancer.
Regulatory Region
145,000 - 150,000 bp
This region contains several regulatory elements including enhancers and promoters that control the expression of nearby genes. It shows high conservation across primate species.
SNP Variant
155,000 bp
rs1802040 (C/T) in the CYP1A1 gene. This variant has been associated with increased cancer risk and altered drug metabolism. T allele is more common in East Asian populations.
