Genes affected

CDSN (HGNC:1802): (corneodesmosin) This gene encodes a protein found in corneodesmosomes, which localize to human epidermis and other cornified squamous epithelia. The encoded protein undergoes a series of cleavages during corneocyte maturation. This gene is highly polymorphic in human populations, and variation has been associated with skin diseases such as psoriasis, hypotrichosis and peeling skin syndrome. The gene is located in the major histocompatibility complex (MHC) class I region on chromosome 6. [provided by RefSeq, Dec 2014]

PSORS1C1 (HGNC:17202): (psoriasis susceptibility 1 candidate 1) This gene is one of several genes thought to confer susceptibility to psoriasis and systemic sclerosis, located on chromosome 6 near the major histocompatibility complex (MHC) class I region. [provided by RefSeq, Sep 2011]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

BS1

Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000301 (44/1459696) while in subpopulation MID AF= 0.000552 (3/5430). AF 95% confidence interval is 0.00034. There are 0 homozygotes in gnomad4_exome. There are 38 alleles in male gnomad4_exome subpopulation. Median coverage is 58. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 511 of the CDSN protein (p.Pro511Leu). This variant is present in population databases (rs754267246, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with CDSN-related conditions. ClinVar contains an entry for this variant (Variation ID: 2191245). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CDSN protein function. 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. -
