Very rare (popmax 0.00333%, amr); Associated with epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency.

How common is DST p.Gly2564= (c.7692G>T) in the general population?

DST p.Gly2564= (c.7692G>T) is very rare (popmax 0.00333%, amr) (gnomAD).

DST p.Gly2564=

Q: What condition is associated with DST p.Gly2564= (c.7692G>T)?

DST p.Gly2564= (c.7692G>T) is associated with epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency, hereditary sensory and autonomic neuropathy type 6 (ClinVar).

Q: How is Epidermolysis bullosa simplex due to BP230 deficiency 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.
