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]

Collection Method:clinical testing

The variant is observed at an extremely low frequency in the gnomAD v4.1.0 dataset (total allele frequency: 0.003%). Predicted Consequence/Location: Intron variant Functional studies provide moderate evidence of the variant having a damaging effect on the gene or gene product (PMID: 15304086). In silico tools predict the variant to alter splicing and produce an abnormal transcript [SpliceAI: 1.00 (>=0.2, moderate evidence for spliceogenicity)]. The variant has been reported to be in trans with a pathogenic variant as either compound heterozygous or homozygous in at least one similarly affected unrelated individual (PMID: 28289593). The variant has been reported at least twice as pathogenic with clinical assertions and evidence for the classification (ClinVar ID: VCV000372516 / PMID: 15304086). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline.

This sequence change falls in intron 15 of the SPINK5 gene. It does not directly change the encoded amino acid sequence of the SPINK5 protein. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has been observed in individuals with Netherton syndrome (PMID: 15304086, 21255986, 26229701, 28289593). It has also been observed to segregate with disease in related individuals. This variant is also known as 1432-13 G>A. ClinVar contains an entry for this variant (Variation ID: 372516). Algorithms developed to predict the effect of variants on gene product structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects SPINK5 function (PMID: 15304086, 21255986). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
