What condition is associated with ADAMTS2 p.Ser374= (c.1122C>T)?

ADAMTS2 p.Ser374= (c.1122C>T) is associated with Ehlers-Danlos syndrome, dermatosparaxis type (ClinVar).

How common is ADAMTS2 p.Ser374= (c.1122C>T) in the general population?

ADAMTS2 p.Ser374= (c.1122C>T) is rare (popmax 0.378%, afr) (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.
