Is SETX p.Ser1179del (c.3532TCT[1]) pathogenic?

SETX p.Ser1179del (c.3532TCT[1]) is classified Uncertain significance in SETX (ClinVar, Single submitter, 1 submitter; last evaluated 2023-08-10). Very rare (popmax 0.000593%, nfe); Associated with amyotrophic lateral sclerosis type 4.

What condition is associated with SETX p.Ser1179del (c.3532TCT[1])?

SETX p.Ser1179del (c.3532TCT[1]) is associated with amyotrophic lateral sclerosis type 4, spinocerebellar ataxia, autosomal recessive, with axonal neuropathy 2 (ClinVar).

How common is SETX p.Ser1179del (c.3532TCT[1]) in the general population?

SETX p.Ser1179del (c.3532TCT[1]) is very rare (popmax 0.000593%, nfe) (gnomAD).

How is Amyotrophic lateral sclerosis type 4 inherited?

Typically Autosomal dominant (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.
