Is DSE p.Arg267Gly (c.799A>G) pathogenic?

DSE p.Arg267Gly (c.799A>G) is classified Pathogenic in DSE (ClinVar, No assertion criteria, 1 submitter; last evaluated 2017-11-08). AlphaMissense: likely pathogenic (0.9811); Absent from gnomAD v4.1; Associated with Ehlers-Danlos syndrome, musculocontractural type 2.

What condition is associated with DSE p.Arg267Gly (c.799A>G)?

DSE p.Arg267Gly (c.799A>G) is associated with Ehlers-Danlos syndrome, musculocontractural type 2 (ClinVar).

How common is DSE p.Arg267Gly (c.799A>G) in the general population?

DSE p.Arg267Gly (c.799A>G) is absent from gnomAD v4.1 (gnomAD).
