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. [PMID 11062481]

|summary||This is a common variant of BRCA2 (HapMap allele frequency of 23%). The variant is weakly associated with an increased chance of breast cancer, and zygosity of the variant is associated with sex of children: male children are more likely to be homozygous for this variant, female children are more likely to be heterozygous.|
