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]

A homozygous missense variation in exon 11 of the INPP5K gene that results in the amino acid substitution of Threonine for Serine at codon 416 was detected. The observed variant c.1247G>C (p.Ser416Thr) has not been reported in the 1000 genomes and gnomAD database respectively. The in silico prediction of the variant are probably damaging by PolyPhen-2 and damaging by SIFT and LRT. The reference codon is conserved across species. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. -
