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

Nov 17, 2022

The c.124G>C (p.G42R) alteration is located in exon 1 (coding exon 1) of the TNKS gene. This alteration results from a G to C substitution at nucleotide position 124, causing the glycine (G) at amino acid position 42 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
