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]

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 17, 2023 | This sequence change creates a premature translational stop signal (p.Thr57Profs*6) in the CDSN gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 473 amino acid(s) of the CDSN protein. This variant is present in population databases (rs606231274, gnomAD 0.06%). This premature translational stop signal has been observed in individuals with autosomal recessive peeling skin syndrome (PMID: 22146835, 31663161). ClinVar contains an entry for this variant (Variation ID: 157564). 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. - |
