Genes affected

REEP1 (HGNC:25786): (receptor accessory protein 1) This gene encodes a mitochondrial protein that functions to enhance the cell surface expression of odorant receptors. Mutations in this gene cause spastic paraplegia autosomal dominant type 31, a neurodegenerative disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1618186).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000046 (7/152222) while in subpopulation AFR AF = 0.000145 (6/41458). AF 95% confidence interval is 0.0000628. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 195 of the REEP1 protein (p.Ala195Ser). This variant is present in population databases (rs757800031, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with REEP1-related conditions. ClinVar contains an entry for this variant (Variation ID: 534214). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
