What condition is associated with NEB p.Asp465= (c.1395C>T)?

NEB p.Asp465= (c.1395C>T) is associated with nemaline myopathy 2 (ClinVar).

How common is NEB p.Asp465= (c.1395C>T) in the general population?

NEB p.Asp465= (c.1395C>T) is ultra-rare (popmax 0.0133%, afr) (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.
