Genes affected

ADSS1 (HGNC:20093): (adenylosuccinate synthase 1) This gene encodes a member of the adenylosuccinate synthase family of proteins. The encoded muscle-specific enzyme plays a role in the purine nucleotide cycle by catalyzing the first step in the conversion of inosine monophosphate (IMP) to adenosine monophosphate (AMP). Mutations in this gene may cause adolescent onset distal myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change affects the initiator methionine of the ADSSL1 mRNA. The next in-frame methionine is located at codon 249. This variant is present in population databases (rs80097179, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with ADSSL1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1681872). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
