Is DBH p.Val195= (c.585G>A) pathogenic?

DBH p.Val195= (c.585G>A) is classified Likely benign in DBH (ClinVar, Single submitter, 1 submitter; last evaluated 2021-04-06). Very rare (popmax 0.00167%, amr); Associated with orthostatic hypotension 1.

What condition is associated with DBH p.Val195= (c.585G>A)?

DBH p.Val195= (c.585G>A) is associated with orthostatic hypotension 1 (ClinVar).

How common is DBH p.Val195= (c.585G>A) in the general population?

DBH p.Val195= (c.585G>A) is very rare (popmax 0.00167%, amr) (gnomAD).

How is Dopamine beta-hydroxylase deficiency 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.
