Is MYO7A p.Asp2142Asn (c.6424G>A) pathogenic?

MYO7A p.Asp2142Asn (c.6424G>A) is classified Benign/Likely benign in MYO7A (ClinVar, Multiple submitters, 7 submitters; last evaluated 2026-02-04). AlphaMissense: likely benign (0.1687); Common (popmax 9.94%, afr) — too common for a highly-penetrant pathogenic allele; Associated with Usher syndrome type 1.

What condition is associated with MYO7A p.Asp2142Asn (c.6424G>A)?

MYO7A p.Asp2142Asn (c.6424G>A) is associated with Usher syndrome type 1, autosomal recessive nonsyndromic hearing loss 2, autosomal dominant nonsyndromic hearing loss 11 (ClinVar).

How is Usher syndrome inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about MYO7A p.Asp2142Asn (c.6424G>A)?

AlphaMissense predicts likely benign (score 0.1687) — an in-silico prediction, not a clinical call.

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.
