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]

Ambry Genetics

Dec 14, 2023

The c.453C>A (p.D151E) alteration is located in exon 5 (coding exon 5) of the ACMSD gene. This alteration results from a C to A substitution at nucleotide position 453, causing the aspartic acid (D) at amino acid position 151 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
