What condition is associated with ADAMTS2 p.Thr728= (c.2184G>A)?

ADAMTS2 p.Thr728= (c.2184G>A) is associated with Ehlers-Danlos syndrome, dermatosparaxis type (ClinVar).

How common is ADAMTS2 p.Thr728= (c.2184G>A) in the general population?

ADAMTS2 p.Thr728= (c.2184G>A) is very rare (popmax 0.00333%, amr) (gnomAD).

How is Dermatosparaxis Ehlers-Danlos syndrome 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.
