Is ADSL c.792+6T>C pathogenic?

ADSL c.792+6T>C is classified Uncertain significance in ADSL (ClinVar, Single submitter, 1 submitter; last evaluated 2022-07-26). Ultra-rare (popmax 0.0103%, nfe); Associated with adenylosuccinate lyase deficiency.

What condition is associated with ADSL c.792+6T>C?

ADSL c.792+6T>C is associated with adenylosuccinate lyase deficiency (ClinVar).

How common is ADSL c.792+6T>C in the general population?

ADSL c.792+6T>C is ultra-rare (popmax 0.0103%, nfe) (gnomAD).

How is Adenylosuccinate lyase deficiency 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.
