What condition is associated with BBS7 p.Arg96= (c.286A>C)?

BBS7 p.Arg96= (c.286A>C) is associated with Bardet-Biedl syndrome (ClinVar).

How common is BBS7 p.Arg96= (c.286A>C) in the general population?

BBS7 p.Arg96= (c.286A>C) is very rare (popmax 0.00333%, amr) (gnomAD).

How is Bardet-Biedl syndrome inherited?

Typically Autosomal recessive, Oligogenic (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.
