Genes affected
ACMSD (HGNC:19288): (aminocarboxymuconate semialdehyde decarboxylase) The neuronal excitotoxin quinolinate is an intermediate in the de novo synthesis pathway of NAD from tryptophan, and has been implicated in the pathogenesis of several neurodegenerative disorders. Quinolinate is derived from alpha-amino-beta-carboxy-muconate-epsilon-semialdehyde (ACMS). ACMSD (ACMS decarboxylase; EC 4.1.1.45) can divert ACMS to a benign catabolite and thus prevent the accumulation of quinolinate from ACMS.[supplied by OMIM, Oct 2004]
CCNT2-AS1 (HGNC:40130): (CCNT2 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.392G>A (p.R131H) alteration is located in exon 5 (coding exon 5) of the ACMSD gene. This alteration results from a G to A substitution at nucleotide position 392, causing the arginine (R) at amino acid position 131 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
