Genes affected
AMPD2 (HGNC:469): (adenosine monophosphate deaminase 2) The protein encoded by this gene is important in purine metabolism by converting AMP to IMP. The encoded protein, which acts as a homotetramer, is one of three AMP deaminases found in mammals. Several transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2024The c.77G>A (p.G26E) alteration is located in exon 1 (coding exon 1) of the AMPD2 gene. This alteration results from a G to A substitution at nucleotide position 77, causing the glycine (G) at amino acid position 26 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
