What condition is associated with DST p.Asp2193= (c.6579T>C)?

DST p.Asp2193= (c.6579T>C) 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.Asp2193= (c.6579T>C) in the general population?

DST p.Asp2193= (c.6579T>C) is very rare (popmax 0.00401%, afr) (gnomAD).

DST p.Asp2193=

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.

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.
