Genes affected

ADSL (HGNC:291): (adenylosuccinate lyase) The protein encoded by this gene belongs to the lyase 1 family. It is an essential enzyme involved in purine metabolism, and catalyzes two non-sequential reactions in the de novo purine biosynthetic pathway: the conversion of succinylaminoimidazole carboxamide ribotide (SAICAR) to aminoimidazole carboxamide ribotide (AICAR) and the conversion of adenylosuccinate (S-AMP) to adenosine monophosphate (AMP). Mutations in this gene are associated with adenylosuccinase deficiency (ADSLD), a disorder marked with psychomotor retardation, epilepsy or autistic features. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]

This variant occurs in a non-coding region of the ADSL gene. It does not change the encoded amino acid sequence of the ADSL protein. This variant is present in population databases (no rsID available, gnomAD 0.001%). This variant has been observed in individual(s) with adenylosuccinate lyase deficiency (PMID: 10958654, 12016589, 23937257). ClinVar contains an entry for this variant (Variation ID: 985789). Studies have shown that this variant alters ADSL gene expression (PMID: 12016589, 25910213). For these reasons, this variant has been classified as Pathogenic. -
