Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP2 PP3_Strong

The NM_020427.3(SLURP1):​c.296G>T​(p.Cys99Phe) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000275 in 1,454,676 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C99Y) has been classified as Pathogenic.

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: Pathogenic. The variant received 11 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
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr8-142741159-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 4607.Status of the report is no_assertion_criteria_provided, 0 stars.
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.995
