Rs28897672

rs28897672 is a SNP causing an amino acid change in the breast cancer 1 BRCA1 gene at amino position 61. The more common rs28897672(T) allele encodes Cys, while the rare rs28897672(G) allele encodes Gly; this variation is also known as Cys61Gly or C61G.

A study of 66 Polish families affected with breast cancer or ovarian cancer, often diagnosed at a relatively young age (< 50 years old), screened for BRCA1 mutations by sequencing. The C61G mutation accounted for 20% of the identified mutations in this group of families.
