What condition is associated with BBS10 p.Ile375= (c.1125C>T)?

BBS10 p.Ile375= (c.1125C>T) is associated with Bardet-Biedl syndrome (ClinVar).

How common is BBS10 p.Ile375= (c.1125C>T) in the general population?

BBS10 p.Ile375= (c.1125C>T) 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.
