Genes affected

MPLKIP (HGNC:16002): (M-phase specific PLK1 interacting protein) The protein encoded by this gene localizes to the centrosome during mitosis and to the midbody during cytokinesis. The protein is phosphorylated by cyclin-dependent kinase 1 during mitosis and subsequently interacts with polo-like kinase 1. The protein is thought to function in regulating mitosis and cytokinesis. Mutations in this gene result in nonphotosensitive trichothiodystrophy. [provided by RefSeq, Nov 2009]

This variant has not been reported in the literature in individuals with MPLKIP-related conditions. 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant is present in population databases (rs750752125, ExAC 0.002%). This sequence change replaces phenylalanine with leucine at codon 178 of the MPLKIP protein (p.Phe178Leu). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and leucine. -
