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 sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 144 of the MPLKIP protein (p.Met144Val). This variant is present in population databases (rs137853117, gnomAD 0.006%). This missense change has been observed in individual(s) with autosomal recessive non-photosensitive trichothiodystrophy (PMID: 15645389). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 1844). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. For these reasons, this variant has been classified as Pathogenic. -
