Genes affected
INPP1 (HGNC:6071): (inositol polyphosphate-1-phosphatase) This gene encodes the enzyme inositol polyphosphate-1-phosphatase, one of the enzymes involved in phosphatidylinositol signaling pathways. This enzyme removes the phosphate group at position 1 of the inositol ring from the polyphosphates inositol 1,4-bisphosphate and inositol 1,3,4-trisphophosphate. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.580G>A (p.G194R) alteration is located in exon 6 (coding exon 4) of the INPP1 gene. This alteration results from a G to A substitution at nucleotide position 580, causing the glycine (G) at amino acid position 194 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
