Rs28897686

rs28897686, also known as E1250X, c.3748G>T,3867G>T and p.Glu1250Ter, is a variant in the BRCA1 gene. The rare G>T variant allele is considered pathogenic by multiple submitters to ClinVar for breast cancer. Note that a G>A allele also is known, however, the clinical significance is unknown.

Note that the 23andMe representation of this SNP is unclear; on the forward strand (in contrast to dbSNP and SNPedia), the alleles being stated as being tested for rs28897686 and i5010145 are C and T, which would correspond to the G>A allele of unknown clinical significance. The G>T allele that is clinically significant does not appear to be tested on a 23andMe microarray.
