Is MYO7A p.Asn535= (c.1605C>T) pathogenic?

MYO7A p.Asn535= (c.1605C>T) is classified Conflicting classifications of pathogenicity in MYO7A (ClinVar, Conflicting submitters, 9 submitters; last evaluated 2026-06-01). Rare (popmax 0.615%, nfe); Associated with Usher syndrome type 1.

What condition is associated with MYO7A p.Asn535= (c.1605C>T)?

MYO7A p.Asn535= (c.1605C>T) is associated with Usher syndrome type 1, autosomal recessive nonsyndromic hearing loss 2, autosomal dominant nonsyndromic hearing loss 11 (ClinVar).

How common is MYO7A p.Asn535= (c.1605C>T) in the general population?

MYO7A p.Asn535= (c.1605C>T) is rare (popmax 0.615%, nfe) (gnomAD).

How is Usher syndrome 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.
