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 GeneticsSep 23, 2023The c.1191A>C (p.K397N) alteration is located in exon 12 (coding exon 12) of the ADSS gene. This alteration results from a A to C substitution at nucleotide position 1191, causing the lysine (K) at amino acid position 397 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
