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]

Jul 13, 2022

The c.19T>G (p.Y7D) alteration is located in exon 1 (coding exon 1) of the ADSS gene. This alteration results from a T to G substitution at nucleotide position 19, causing the tyrosine (Y) at amino acid position 7 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
