What condition is associated with EMD p.Phe61= (c.183C>T)?

EMD p.Phe61= (c.183C>T) is associated with X-linked Emery-Dreifuss muscular dystrophy (ClinVar).

How common is EMD p.Phe61= (c.183C>T) in the general population?

EMD p.Phe61= (c.183C>T) is ultra-rare (popmax 0.0354%, sas) (gnomAD).

How is Emery-Dreifuss muscular dystrophy inherited?

Typically Autosomal dominant, 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.
