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 GeneticsNov 27, 2024The c.207T>G (p.F69L) alteration is located in exon 4 (coding exon 2) of the INPP1 gene. This alteration results from a T to G substitution at nucleotide position 207, causing the phenylalanine (F) at amino acid position 69 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
