Variant 17-42581920-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_178126.4(RETREG3):c.1294C>T(p.Arg432Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,614,042 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/20 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. R432Q) has been classified as Uncertain significance.

Ambry Genetics

Aug 01, 2023

The c.1294C>T (p.R432W) alteration is located in exon 9 (coding exon 9) of the FAM134C gene. This alteration results from a C to T substitution at nucleotide position 1294, causing the arginine (R) at amino acid position 432 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
