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]

Ambry Genetics

Dec 15, 2022

The c.49G>A (p.D17N) alteration is located in exon 1 (coding exon 1) of the ADSS gene. This alteration results from a G to A substitution at nucleotide position 49, causing the aspartic acid (D) at amino acid position 17 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
