Genes affected
OSBPL7 (HGNC:16387): (oxysterol binding protein like 7) This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Like most members, the encoded protein contains an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain. Two transcript variants encoding the same isoform have been identified. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2023The c.1340G>A (p.R447H) alteration is located in exon 14 (coding exon 13) of the OSBPL7 gene. This alteration results from a G to A substitution at nucleotide position 1340, causing the arginine (R) at amino acid position 447 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
