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]

The c.1250C>T (p.A417V) alteration is located in exon 12 (coding exon 12) of the ADSS gene. This alteration results from a C to T substitution at nucleotide position 1250, causing the alanine (A) at amino acid position 417 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
