Genes affected

SLURP1 (HGNC:18746): (secreted LY6/PLAUR domain containing 1) The protein encoded by this gene is a member of the Ly6/uPAR family but lacks a GPI-anchoring signal sequence. It is thought that this secreted protein contains antitumor activity. Mutations in this gene have been associated with Mal de Meleda, a rare autosomal recessive skin disorder. This gene maps to the same chromosomal region as several members of the Ly6/uPAR family of glycoprotein receptors. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Uncertain_significance. The variant received 3 ACMG points.

• PM1: In a chain Secreted Ly-6/uPAR-related protein 1 (size 80) in uniprot entity SLUR1_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_020427.3
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.59094 (below the threshold of 3.09). Trascript score misZ: 0.80412 (below the threshold of 3.09). GenCC associations: The gene is linked to mal de Meleda, palmoplantar keratosis, hereditary palmoplantar keratoderma, Gamborg-Nielsen type.
• BP4: Computational evidence support a benign effect (MetaRNN=0.18492243).
