What condition is associated with LMOD3 p.Pro476= (c.1428G>A)?

LMOD3 p.Pro476= (c.1428G>A) is associated with nemaline myopathy 10 (ClinVar).

How common is LMOD3 p.Pro476= (c.1428G>A) in the general population?

LMOD3 p.Pro476= (c.1428G>A) is very rare (popmax 0.00805%, nfe) (gnomAD).

How is Severe congenital nemaline myopathy 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.
