AlphaMissense: likely benign (0.0737); Very rare (popmax 6.2e-05%); Associated with autosomal recessive mendelian susceptibility to mycobacterial diseases due to complete RORgamma receptor deficiency.

How common is RORC p.His322Arg (c.965A>G) in the general population?

RORC p.His322Arg (c.965A>G) is very rare (popmax 6.2e-05%) (gnomAD).

What do computational predictors say about RORC p.His322Arg (c.965A>G)?

AlphaMissense predicts likely benign (score 0.0737) — an in-silico prediction, not a clinical call.

RORC p.His322Arg

Q: What condition is associated with RORC p.His322Arg (c.965A>G)?

RORC p.His322Arg (c.965A>G) is associated with autosomal recessive mendelian susceptibility to mycobacterial diseases due to complete RORgamma receptor deficiency (ClinVar).

Q: How is Mendelian susceptibility to mycobacterial diseases due to complete RORgamma receptor deficiency inherited?

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

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
