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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 29, 2023 | The c.1045G>A (p.A349T) alteration is located in exon 10 (coding exon 10) of the ADSS gene. This alteration results from a G to A substitution at nucleotide position 1045, causing the alanine (A) at amino acid position 349 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
