Genes affected
MAPKBP1 (HGNC:29536): (mitogen-activated protein kinase binding protein 1) This gene encodes a scaffold protein that regulates the JNK (c-Jun N-terminal kinase) and NOD2 (nucleotide-binding oligomerization domain-containing protein 2) signaling pathways. The encoded protein interacts with another related JNK pathway scaffold protein, WDR62, via a conserved dimerization domain, and enhances JNK signaling. This protein may play a role in bacterial immunity by binding to the NOD2 receptor and negatively regulating downstream antibacterial and pro-inflammatory signaling. Mutations in this gene that impair cellular localization of the encoded protein cause a form of nephronophthisis, an autosomal-recessive kidney disorder, in human patients.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 06, 2022The c.263G>A (p.S88N) alteration is located in exon 4 (coding exon 3) of the MAPKBP1 gene. This alteration results from a G to A substitution at nucleotide position 263, causing the serine (S) at amino acid position 88 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 06, 2022This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 88 of the MAPKBP1 protein (p.Ser88Asn). This variant is present in population databases (rs200453027, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with MAPKBP1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
