Genes affected
INPP4A (HGNC:6074): (inositol polyphosphate-4-phosphatase type I A) This gene encodes an Mg++ independent enzyme that hydrolyzes the 4-position phosphate from the inositol ring of phosphatidylinositol 3,4-bisphosphate, inositol 1,3,4-trisphosphate, and inositol 3,4-bisphosphate. Multiple transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Aug 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.887C>T (p.T296I) alteration is located in exon 11 (coding exon 9) of the INPP4A gene. This alteration results from a C to T substitution at nucleotide position 887, causing the threonine (T) at amino acid position 296 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
