Genes affected
INPP5K (HGNC:33882): (inositol polyphosphate-5-phosphatase K) This gene encodes a protein with 5-phosphatase activity toward polyphosphate inositol. The protein localizes to the cytosol in regions lacking actin stress fibers. It is thought that this protein may negatively regulate the actin cytoskeleton. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Oct 2008]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 26, 2024The c.1202G>A (p.S401N) alteration is located in exon 11 (coding exon 11) of the INPP5K gene. This alteration results from a G to A substitution at nucleotide position 1202, causing the serine (S) at amino acid position 401 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
