Genes affected
PIP5K1C (HGNC:8996): (phosphatidylinositol-4-phosphate 5-kinase type 1 gamma) This locus encodes a type I phosphatidylinositol 4-phosphate 5-kinase. The encoded protein catalyzes phosphorylation of phosphatidylinositol 4-phosphate, producing phosphatidylinositol 4,5-bisphosphate. This enzyme is found at synapses and has been found to play roles in endocytosis and cell migration. Mutations at this locus have been associated with lethal congenital contractural syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Sep 2010]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.1997G>A (p.S666N) alteration is located in exon 17 (coding exon 17) of the PIP5K1C gene. This alteration results from a G to A substitution at nucleotide position 1997, causing the serine (S) at amino acid position 666 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
