What condition is associated with BRCA2 p.Ser2072= (c.6216C>G)?

BRCA2 p.Ser2072= (c.6216C>G) is associated with breast-ovarian cancer, familial, susceptibility to, 2, hereditary breast ovarian cancer syndrome, hereditary neoplastic syndrome (ClinVar).

How common is BRCA2 p.Ser2072= (c.6216C>G) in the general population?

BRCA2 p.Ser2072= (c.6216C>G) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
