Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_033396.3(TNKS1BP1):c.4841G>A(p.Arg1614Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000434 in 1,613,660 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign 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. R1614W) has been classified as Uncertain significance.

Genes affected

TNKS1BP1 (HGNC:19081): (tankyrase 1 binding protein 1) Enables ankyrin repeat binding activity and enzyme binding activity. Involved in cellular response to ionizing radiation; double-strand break repair; and positive regulation of protein phosphorylation. Located in several cellular components, including actin cytoskeleton; adherens junction; and heterochromatin. Part of CCR4-NOT complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.4841G>A (p.R1614Q) alteration is located in exon 9 (coding exon 8) of the TNKS1BP1 gene. This alteration results from a G to A substitution at nucleotide position 4841, causing the arginine (R) at amino acid position 1614 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
