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.707A>T (p.Y236F) alteration is located in exon 8 (coding exon 8) of the ADSS gene. This alteration results from a A to T substitution at nucleotide position 707, causing the tyrosine (Y) at amino acid position 236 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
