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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.551G>T (p.S184I) alteration is located in exon 4 (coding exon 3) of the IP6K1 gene. This alteration results from a G to T substitution at nucleotide position 551, causing the serine (S) at amino acid position 184 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
