Genes affected

TNKS (HGNC:11941): (tankyrase) Enables histone binding activity; pentosyltransferase activity; and zinc ion binding activity. Involved in several processes, including negative regulation of maintenance of mitotic sister chromatid cohesion, telomeric; protein ADP-ribosylation; and regulation of nucleobase-containing compound metabolic process. Acts upstream of or within peptidyl-serine phosphorylation; peptidyl-threonine phosphorylation; and protein ADP-ribosylation. Located in several cellular components, including chromosome, telomeric region; mitotic spindle pole; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 02, 2021

The c.206A>G (p.D69G) alteration is located in exon 1 (coding exon 1) of the TNKS gene. This alteration results from a A to G substitution at nucleotide position 206, causing the aspartic acid (D) at amino acid position 69 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
