Genes affected
PITPNM2 (HGNC:21044): (phosphatidylinositol transfer protein membrane associated 2) PITPNM2 belongs to a family of membrane-associated phosphatidylinositol transfer domain-containing proteins that share homology with the Drosophila retinal degeneration B (rdgB) protein (Ocaka et al., 2005 [PubMed 15627748]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 21, 2024The c.3863G>A (p.R1288H) alteration is located in exon 25 (coding exon 24) of the PITPNM2 gene. This alteration results from a G to A substitution at nucleotide position 3863, causing the arginine (R) at amino acid position 1288 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
