Genes affected
OSBPL3 (HGNC:16370): (oxysterol binding protein like 3) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. The encoded protein is involved in the regulation of cell adhesion and organization of the actin cytoskeleton. Alternative splicing results in multiple transcript variants.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.2521C>T (p.R841W) alteration is located in exon 22 (coding exon 21) of the OSBPL3 gene. This alteration results from a C to T substitution at nucleotide position 2521, causing the arginine (R) at amino acid position 841 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
