Variant 7-40133070-A-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The ENST00000306984.8(MPLKIP):c.529T>C(p.Tyr177His) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,512 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y177C) has been classified as Uncertain significance.

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]

The c.529T>C (p.Y177H) alteration is located in exon 2 (coding exon 2) of the MPLKIP gene. This alteration results from a T to C substitution at nucleotide position 529, causing the tyrosine (Y) at amino acid position 177 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
