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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 21, 2023The c.910G>A (p.V304I) alteration is located in exon 9 (coding exon 9) of the ADSS gene. This alteration results from a G to A substitution at nucleotide position 910, causing the valine (V) at amino acid position 304 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
