Genes affected
PITPNM1 (HGNC:9003): (phosphatidylinositol transfer protein membrane associated 1) PITPNM1 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 GeneticsNov 08, 2021The c.2968G>A (p.A990T) alteration is located in exon 20 (coding exon 19) of the PITPNM1 gene. This alteration results from a G to A substitution at nucleotide position 2968, causing the alanine (A) at amino acid position 990 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
