Genes affected

ITPK1 (HGNC:6177): (inositol-tetrakisphosphate 1-kinase) This gene encodes an enzyme that belongs to the inositol 1,3,4-trisphosphate 5/6-kinase family. This enzyme regulates the synthesis of inositol tetraphosphate, and downstream products, inositol pentakisphosphate and inositol hexakisphosphate. Inositol metabolism plays a role in the development of the neural tube. Disruptions in this gene are thought to be associated with neural tube defects. A pseudogene of this gene has been identified on chromosome X. [provided by RefSeq, Jul 2016]

The c.1135G>A (p.G379S) alteration is located in exon 11 (coding exon 10) of the ITPK1 gene. This alteration results from a G to A substitution at nucleotide position 1135, causing the glycine (G) at amino acid position 379 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
