Is BRCA2 p.Asp2451His (c.7351G>C) pathogenic?

BRCA2 p.Asp2451His (c.7351G>C) is classified Uncertain significance in BRCA2 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2024-03-14). AlphaMissense: likely benign (0.1004); No allele count reported in gnomAD v4.1 (AN 1,609,888); Associated with hereditary breast ovarian cancer syndrome.

What condition is associated with BRCA2 p.Asp2451His (c.7351G>C)?

BRCA2 p.Asp2451His (c.7351G>C) is associated with hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA2 p.Asp2451His (c.7351G>C) in the general population?

BRCA2 p.Asp2451His (c.7351G>C) is no allele count reported in gnomAD v4.1 (AN 1,609,888) (gnomAD).

How is Hereditary breast and/or ovarian cancer syndrome inherited?

Typically Autosomal dominant (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about BRCA2 p.Asp2451His (c.7351G>C)?

AlphaMissense predicts likely benign (score 0.1004) — an in-silico prediction, not a clinical call.
