Genes affected

KIFBP (HGNC:23419): (kinesin family binding protein) This gene encodes a kinesin family member 1 binding protein that is characterized by two tetratrico peptide repeats. The encoded protein localizes to the mitochondria and may be involved in regulating transport of the mitochondria. Mutations in this gene are associated with Goldberg-Shprintzen megacolon syndrome.

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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 447658). This variant has not been reported in the literature in individuals affected with KIF1BP-related conditions. This variant is present in population databases (rs368405054, gnomAD 0.03%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 541 of the KIF1BP protein (p.Arg541His). -
