Is DBH p.Pro607Ser (c.1819C>T) pathogenic?

DBH p.Pro607Ser (c.1819C>T) is classified Benign/Likely benign in DBH (ClinVar, Multiple submitters, 4 submitters; last evaluated 2026-01-16). AlphaMissense: likely benign (0.1198); Rare (popmax 0.123%, nfe); Associated with orthostatic hypotension 1.

What condition is associated with DBH p.Pro607Ser (c.1819C>T)?

DBH p.Pro607Ser (c.1819C>T) is associated with orthostatic hypotension 1 (ClinVar).

How common is DBH p.Pro607Ser (c.1819C>T) in the general population?

DBH p.Pro607Ser (c.1819C>T) is rare (popmax 0.123%, nfe) (gnomAD).

How is Dopamine beta-hydroxylase deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

What do computational predictors say about DBH p.Pro607Ser (c.1819C>T)?

AlphaMissense predicts likely benign (score 0.1198) — an in-silico prediction, not a clinical call.

Finnish shows a higher raw frequency than the grpmax group above it. gnomAD excludes bottlenecked groups — Finnish, Ashkenazi Jewish, Amish and “Remaining individuals” — from grpmax, because founder effects make their frequencies unrepresentative for filtering. The table is sorted by frequency, so an excluded group can sit above the grpmax row.

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.
