RORC p.Asp155=

Q: What condition is associated with RORC p.Asp155= (c.465C>T)?

RORC p.Asp155= (c.465C>T) 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.

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.
