INF2 p.Ser811=

Q: What condition is associated with INF2 p.Ser811= (c.2433C>T)?

INF2 p.Ser811= (c.2433C>T) is associated with Charcot-Marie-Tooth disease dominant intermediate E, focal segmental glomerulosclerosis 5 (ClinVar).

Q: How is Autosomal dominant intermediate Charcot-Marie-Tooth disease type E inherited?

Typically Autosomal dominant, Not applicable (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.
