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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.872

May 16, 2024

The c.848T>C (p.L283P) alteration is located in exon 11 (coding exon 11) of the ERLIN1 gene. This alteration results from a T to C substitution at nucleotide position 848, causing the leucine (L) at amino acid position 283 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
