Genes affected

AK5 (HGNC:365): (adenylate kinase 5) This gene encodes a member of the adenylate kinase family, which is involved in regulating the adenine nucleotide composition within a cell by catalyzing the reversible transfer of phosphate groups among adenine nucleotides. This member is related to the UMP/CMP kinase of several species. It is located in the cytosol and expressed exclusively in brain. Alternatively spliced transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.1291C>T (p.R431C) alteration is located in exon 11 (coding exon 11) of the AK5 gene. This alteration results from a C to T substitution at nucleotide position 1291, causing the arginine (R) at amino acid position 431 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
