Genes affected

AK9 (HGNC:33814): (adenylate kinase 9) The protein encoded by this gene catalyzes the interconversion of nucleosides, possessing both nucleoside monophosphate and diphosphate kinase activities. The encoded protein uses these interconversions to maintain nucleoside homeostasis. [provided by RefSeq, Jul 2016]

The c.4645C>T (p.H1549Y) alteration is located in exon 35 (coding exon 34) of the AK9 gene. This alteration results from a C to T substitution at nucleotide position 4645, causing the histidine (H) at amino acid position 1549 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
