Variant 2-74426536-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The ENST00000272430.10(RTKN):c.1399A>G(p.Ile467Val) variant causes a missense change. The variant allele was found at a frequency of 0.00000194 in 1,547,040 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. I467T) has been classified as Uncertain significance.

Genes affected

RTKN (HGNC:10466): (rhotekin) This gene encodes a scaffold protein that interacts with GTP-bound Rho proteins. Binding of this protein inhibits the GTPase activity of Rho proteins. This protein may interfere with the conversion of active, GTP-bound Rho to the inactive GDP-bound form by RhoGAP. Rho proteins regulate many important cellular processes, including cytokinesis, transcription, smooth muscle contraction, cell growth and transformation. Dysregulation of the Rho signal transduction pathway has been implicated in many forms of cancer. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.1399A>G (p.I467V) alteration is located in exon 12 (coding exon 12) of the RTKN gene. This alteration results from a A to G substitution at nucleotide position 1399, causing the isoleucine (I) at amino acid position 467 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
