Is DBH p.Leu484Pro (c.1451T>C) pathogenic?

DBH p.Leu484Pro (c.1451T>C) is classified Uncertain significance in DBH (ClinVar, Multiple submitters, 3 submitters; last evaluated 2024-09-11). AlphaMissense: likely benign (0.2028); Ultra-rare (popmax 0.0108%, nfe); Associated with orthostatic hypotension 1.

What condition is associated with DBH p.Leu484Pro (c.1451T>C)?

DBH p.Leu484Pro (c.1451T>C) is associated with orthostatic hypotension 1 (ClinVar).

How common is DBH p.Leu484Pro (c.1451T>C) in the general population?

DBH p.Leu484Pro (c.1451T>C) is ultra-rare (popmax 0.0108%, 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.Leu484Pro (c.1451T>C)?

AlphaMissense predicts likely benign (score 0.2028) — an in-silico prediction, not a clinical call.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

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.
