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 Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BP6: Variant 10-100152509-C-T is Benign according to our data. Variant chr10-100152509-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1693026.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00492 (749/152322) while in subpopulation AFR AF= 0.0171 (711/41566). AF 95% confidence interval is 0.0161. There are 8 homozygotes in gnomad4. There are 373 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 8 AR gene
