Is DMD p.Glu6= (c.18A>G) pathogenic?

DMD p.Glu6= (c.18A>G) is classified Likely benign in DMD (ClinVar, Single submitter, 1 submitter; last evaluated 2021-08-16). Absent from gnomAD v4.1; Associated with Duchenne muscular dystrophy.

What condition is associated with DMD p.Glu6= (c.18A>G)?

DMD p.Glu6= (c.18A>G) is associated with Duchenne muscular dystrophy (ClinVar).

How common is DMD p.Glu6= (c.18A>G) in the general population?

DMD p.Glu6= (c.18A>G) is absent from gnomAD v4.1 (gnomAD).

How is Duchenne muscular dystrophy inherited?

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