Is PRODH p.Pro537= (c.1611G>A) pathogenic?

PRODH p.Pro537= (c.1611G>A) is classified Likely benign in PRODH (ClinVar, Single submitter, 1 submitter; last evaluated 2025-03-21). Very rare (popmax 0.00138%, nfe); Associated with hyperprolinemia type 1.

What condition is associated with PRODH p.Pro537= (c.1611G>A)?

PRODH p.Pro537= (c.1611G>A) is associated with hyperprolinemia type 1 (ClinVar).

How common is PRODH p.Pro537= (c.1611G>A) in the general population?

PRODH p.Pro537= (c.1611G>A) is very rare (popmax 0.00138%, nfe) (gnomAD).

How is Hyperprolinemia 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.
