Genes affected

INPP5F (HGNC:17054): (inositol polyphosphate-5-phosphatase F) The protein encoded by this gene is an inositol 1,4,5-trisphosphate (InsP3) 5-phosphatase and contains a Sac domain. The activity of this protein is specific for phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 3,4,5-trisphosphate. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2011]

Collection Method: clinical testing

The c.422T>A (p.V141E) alteration is located in exon 4 (coding exon 4) of the INPP5F gene. This alteration results from a T to A substitution at nucleotide position 422, causing the valine (V) at amino acid position 141 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
