Genes affected
ATIC (HGNC:794): (5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/IMP cyclohydrolase) This gene encodes a bifunctional protein that catalyzes the last two steps of the de novo purine biosynthetic pathway. The N-terminal domain has phosphoribosylaminoimidazolecarboxamide formyltransferase activity, and the C-terminal domain has IMP cyclohydrolase activity. A mutation in this gene results in AICA-ribosiduria. [provided by RefSeq, Sep 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.164C>T (p.T55M) alteration is located in exon 3 (coding exon 3) of the ATIC gene. This alteration results from a C to T substitution at nucleotide position 164, causing the threonine (T) at amino acid position 55 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
