Genes affected

IP6K1 (HGNC:18360): (inositol hexakisphosphate kinase 1) This gene encodes a member of the inositol phosphokinase family. The encoded protein may be responsible for the conversion of inositol hexakisphosphate (InsP6) to diphosphoinositol pentakisphosphate (InsP7/PP-InsP5). It may also convert 1,3,4,5,6-pentakisphosphate (InsP5) to PP-InsP4. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jun 2011]

The c.1106C>T (p.A369V) alteration is located in exon 6 (coding exon 5) of the IP6K1 gene. This alteration results from a C to T substitution at nucleotide position 1106, causing the alanine (A) at amino acid position 369 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
