Genes affected

RIPK1 (HGNC:10019): (receptor interacting serine/threonine kinase 1) This gene encodes a member of the receptor-interacting protein (RIP) family of serine/threonine protein kinases. The encoded protein plays a role in inflammation and cell death in response to tissue damage, pathogen recognition, and as part of developmental regulation. RIPK1/RIPK3 kinase-mediated necrosis is referred to as necroptosis. Genetic disruption of this gene in mice results in death shortly after birth. [provided by RefSeq, Aug 2017]

This sequence change affects the initiator methionine of the RIPK1 mRNA. The next in-frame methionine is located at codon 5. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RIPK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1432706). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -
