Genes affected

SPINK5 (HGNC:15464): (serine peptidase inhibitor Kazal type 5) This gene encodes a multidomain serine protease inhibitor that contains 15 potential inhibitory domains. The encoded preproprotein is proteolytically processed to generate multiple protein products, which may exhibit unique activities and specificities. These proteins may play a role in skin and hair morphogenesis, as well as anti-inflammatory and antimicrobial protection of mucous epithelia. Mutations in this gene may result in Netherton syndrome, a disorder characterized by ichthyosis, defective cornification, and atopy. This gene is present in a gene cluster on chromosome 5. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2015]

Netherton syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Sep 21, 2016	The SPINK5 c.652C>T (p. Arg218Ter) stop-gained variant has been reported in two studies and is found in a total of 11 individuals with Netherton syndrome, including eight homozygotes and three compound heterozygotes, including a sibling pair (Sprecher et al. 2001; Hannula-Jouppi et al. 2016). The p.Arg218Ter variant was absent from at least 50 controls and is reported at a frequency of 0.00005 in the European (non-Finnish) population of the Exome Aggregation Consortium. Based on the evidence and due to the potential impact of stop-gained variants, the p.Arg218Ter variant is classified as pathogenic for Netherton syndrome. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
