Genes affected

ERLIN1 (HGNC:16947): (ER lipid raft associated 1) The protein encoded by this gene is part of a protein complex that mediates degradation of inositol 1,4,5-trisphosphate receptors in the endoplasmic reticulum. The encoded protein also binds cholesterol and regulates the SREBP signaling pathway, which promotes cellular cholesterol homeostasis. Defects in this gene have been associated with spastic paraplegia 62. [provided by RefSeq, Dec 2016]

The c.856A>C (p.K286Q) alteration is located in exon 11 (coding exon 11) of the ERLIN1 gene. This alteration results from a A to C substitution at nucleotide position 856, causing the lysine (K) at amino acid position 286 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces lysine with glutamine at codon 286 of the ERLIN1 protein (p.Lys286Gln). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamine. This variant is present in population databases (rs774243081, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with ERLIN1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
