Rs144848

This SNP, a variant in the BRCA2 gene, is 1 of 25 SNPs reported to represent independently minor, but cumulatively significant, increased risk for breast cancer.

For details of all 25 SNPs in this group, along with the two methods used to calculate overall risk estimates for breast cancer, refer to the SNPedia breast cancer entry.

For this particular SNP, the risk (minor) allele is (G), encoding the His; the SNP is also known as N372H or Asn372His.

In a separate study, rs144848(G;G) homozygotes were determined to have a 1.31x increased risk (CI: 1.07-1.61) for breast cancer greater risk compared to (T;T) genotypes. Interestingly, in normal females of all ages there is a significant deficiency of homozygotes compared with that expected from Hardy-Weinberg equilibrium, whereas in males there is an excess of homozygotes (with an estimated fitness of 0.82 in females and 1.38 in males). This implies that rs144848 affects fetal survival in a sex-dependent manner.
