Variant 3-129002028-C-T details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_001377500.1(EFCC1):c.400C>T(p.Arg134Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000175 in 1,544,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/18 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. R134P) has been classified as Uncertain significance.

The c.400C>T (p.R134C) alteration is located in exon 1 (coding exon 1) of the EFCC1 gene. This alteration results from a C to T substitution at nucleotide position 400, causing the arginine (R) at amino acid position 134 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
