Genes affected

CDK14 (HGNC:8883): (cyclin dependent kinase 14) Enables cyclin binding activity and cyclin-dependent protein serine/threonine kinase activity. Involved in G2/M transition of mitotic cell cycle and regulation of canonical Wnt signaling pathway. Located in cytosol; nucleoplasm; and plasma membrane. Part of cytoplasmic cyclin-dependent protein kinase holoenzyme complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.86T>C (p.M29T) alteration is located in exon 2 (coding exon 2) of the CDK14 gene. This alteration results from a T to C substitution at nucleotide position 86, causing the methionine (M) at amino acid position 29 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
