What condition is associated with DST p.Glu2405= (c.7215G>A)?

DST p.Glu2405= (c.7215G>A) is associated with hereditary sensory and autonomic neuropathy type 6, epidermolysis bullosa simplex 3, localized or generalized intermediate, with BP230 deficiency (ClinVar).

How common is DST p.Glu2405= (c.7215G>A) in the general population?

DST p.Glu2405= (c.7215G>A) is ultra-rare (popmax 0.0136%, nfe) (gnomAD).

DST p.Glu2405=

Q: How is Hereditary sensory and autonomic neuropathy type 6 inherited?

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

Finnish shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
