Genes affected

ADSS2 (HGNC:292): (adenylosuccinate synthase 2) This gene encodes the enzyme adenylosuccinate synthetase which catalyzes the first committed step in the conversion of inosine monophosphate to adenosine monophosphate. A pseudogene of this gene is found on chromosome 17.[provided by RefSeq, Nov 2010]

Nov 29, 2021

The c.145C>G (p.L49V) alteration is located in exon 1 (coding exon 1) of the ADSS gene. This alteration results from a C to G substitution at nucleotide position 145, causing the leucine (L) at amino acid position 49 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
