Is PALB2 p.Asp360= (c.1080C>T) pathogenic?

PALB2 p.Asp360= (c.1080C>T) is classified Benign/Likely benign in PALB2 (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-01-13). Absent from gnomAD v4.1; Associated with hereditary breast carcinoma.

What condition is associated with PALB2 p.Asp360= (c.1080C>T)?

PALB2 p.Asp360= (c.1080C>T) is associated with hereditary breast carcinoma, hereditary neoplastic syndrome (ClinVar).

How common is PALB2 p.Asp360= (c.1080C>T) in the general population?

PALB2 p.Asp360= (c.1080C>T) is absent from gnomAD v4.1 (gnomAD).

How is Hereditary breast cancer inherited?

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