Genes affected
OSBPL1A (HGNC:16398): (oxysterol binding protein like 1A) 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, although some members contain only the sterol-binding domain. Transcript variants derived from alternative promoter usage and/or alternative splicing exist; they encode different isoforms. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.1790C>G (p.S597C) alteration is located in exon 19 (coding exon 18) of the OSBPL1A gene. This alteration results from a C to G substitution at nucleotide position 1790, causing the serine (S) at amino acid position 597 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
