What condition is associated with AVPR2 p.Leu35= (c.105G>A)?

AVPR2 p.Leu35= (c.105G>A) is associated with diabetes insipidus, nephrogenic, X-linked, nephrogenic syndrome of inappropriate antidiuresis (ClinVar).

How common is AVPR2 p.Leu35= (c.105G>A) in the general population?

AVPR2 p.Leu35= (c.105G>A) is rare (popmax 0.41%, afr) (gnomAD).

How is Arginine vasopressin resistance inherited?

Typically Autosomal dominant, 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.
