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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2022The c.1885G>A (p.V629I) alteration is located in exon 17 (coding exon 16) of the OSBPL3 gene. This alteration results from a G to A substitution at nucleotide position 1885, causing the valine (V) at amino acid position 629 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
