Is AUH p.Pro32= (c.96G>A) pathogenic?

AUH p.Pro32= (c.96G>A) is classified Likely benign in AUH (ClinVar, Single submitter, 1 submitter; last evaluated 2023-03-22). Very rare (popmax 0.00533%, nfe); Associated with 3-methylglutaconic aciduria type 1.

What condition is associated with AUH p.Pro32= (c.96G>A)?

AUH p.Pro32= (c.96G>A) is associated with 3-methylglutaconic aciduria type 1 (ClinVar).

How common is AUH p.Pro32= (c.96G>A) in the general population?

AUH p.Pro32= (c.96G>A) is very rare (popmax 0.00533%, nfe) (gnomAD).

How is 3-methylglutaconic aciduria type 1 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.
