Is CDK4 p.His292Arg (c.875A>G) pathogenic?

CDK4 p.His292Arg (c.875A>G) is classified Uncertain significance in CDK4 (ClinVar, Multiple submitters, 2 submitters; last evaluated 2023-07-31). AlphaMissense: likely pathogenic (0.7789); Very rare (popmax 8.48e-05%, nfe); Associated with familial melanoma.

What condition is associated with CDK4 p.His292Arg (c.875A>G)?

CDK4 p.His292Arg (c.875A>G) is associated with familial melanoma, hereditary neoplastic syndrome (ClinVar).

How common is CDK4 p.His292Arg (c.875A>G) in the general population?

CDK4 p.His292Arg (c.875A>G) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

How is Familial melanoma inherited?

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

What do computational predictors say about CDK4 p.His292Arg (c.875A>G)?

AlphaMissense predicts likely pathogenic (score 0.7789) — an in-silico prediction, not a clinical call.

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.
