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.159C>A (p.D53E) alteration is located in exon 1 (coding exon 1) of the ADSS gene. This alteration results from a C to A substitution at nucleotide position 159, causing the aspartic acid (D) at amino acid position 53 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
