Is SETX p.Ala2592Val (c.7775C>T) pathogenic?

SETX p.Ala2592Val (c.7775C>T) is classified Conflicting classifications of pathogenicity in SETX (ClinVar, Conflicting submitters, 3 submitters; last evaluated 2023-02-08). AlphaMissense: likely benign (0.0981); Very rare (popmax 0.00133%, afr); Associated with amyotrophic lateral sclerosis type 4.

What condition is associated with SETX p.Ala2592Val (c.7775C>T)?

SETX p.Ala2592Val (c.7775C>T) is associated with amyotrophic lateral sclerosis type 4, spinocerebellar ataxia, autosomal recessive, with axonal neuropathy 2 (ClinVar).

How common is SETX p.Ala2592Val (c.7775C>T) in the general population?

SETX p.Ala2592Val (c.7775C>T) is very rare (popmax 0.00133%, afr) (gnomAD).

How is Amyotrophic lateral sclerosis type 4 inherited?

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

What do computational predictors say about SETX p.Ala2592Val (c.7775C>T)?

AlphaMissense predicts likely benign (score 0.0981) — an in-silico prediction, not a clinical call.

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.
