Genes affected

DYNLT4 (HGNC:32315): (dynein light chain Tctex-type 4) Enables protein phosphatase 1 binding activity. Predicted to be involved in microtubule-based movement. Located in acrosomal vesicle; cytoskeleton; and sperm flagellum. [provided by Alliance of Genome Resources, Apr 2022]

DYNLT4 links:

PLK3 (HGNC:2154): (polo like kinase 3) The protein encoded by this gene is a member of the highly conserved polo-like kinase family of serine/threonine kinases. Members of this family are characterized by an amino-terminal kinase domain and a carboxy-terminal bipartite polo box domain that functions as a substrate-binding motif and a cellular localization signal. Polo-like kinases are important regulators of cell cycle progression. This gene has also been implicated in stress responses and double-strand break repair. In human cell lines, this protein is reported to associate with centrosomes in a microtubule-dependent manner, and during mitosis, the protein becomes localized to the mitotic apparatus. Expression of a kinase-defective mutant results in abnormal cell morphology caused by changes in microtubule dynamics and mitotic arrest followed by apoptosis. [provided by RefSeq, Sep 2015]

The c.641C>T (p.T214M) alteration is located in exon 2 (coding exon 1) of the TCTEX1D4 gene. This alteration results from a C to T substitution at nucleotide position 641, causing the threonine (T) at amino acid position 214 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
