HGNC:291 (protein-coding gene)

adenylosuccinate lyase

Unique Cases:: 3

Disorders:: ID, ASD, EP

Last Updated:: January 24, 2024

Gene Summary:

DBD Genes Classification: ADSL is a High Confidence candidate gene classified as Tier AR. AR genes have autosomal recessive inheritance.

Gene Function: Catalyzes two non-sequential steps in de novo AMP synthesis: converts (S)-2-(5-amino-1-(5-phospho-D-ribosyl)imidazole-4- carboxamido)succinate (SAICAR) to fumarate plus 5-amino-1-(5-phospho-D- ribosyl)imidazole-4-carboxamide, and thereby also contributes to de novo IMP synthesis, and converts succinyladenosine monophosphate (SAMP) to AMP and fumarate. {ECO:0000269|PubMed:10888601}.
