Genes affected

AGMO (HGNC:33784): (alkylglycerol monooxygenase) The protein encoded by this gene is a tetrahydrobiopterin- and iron-dependent enzyme that cleaves the ether bond of alkylglycerols. Sequence comparisons distinguish this protein as forming a third, distinct class of tetrahydrobiopterin-dependent enzymes. Variations in this gene have been associated with decreased glucose-stimulated insulin response, type 2 diabetes, and susceptibility to intracranial aneurysms. [provided by RefSeq, Aug 2012]

The c.1187G>A (p.R396H) alteration is located in exon 12 (coding exon 12) of the AGMO gene. This alteration results from a G to A substitution at nucleotide position 1187, causing the arginine (R) at amino acid position 396 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
