Variant 1-119808750-C-T 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_032044.4(REG4):c.20G>A(p.Arg7Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000123 in 1,461,650 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. R7W) has been classified as Likely benign.

Ambry Genetics

Jun 07, 2024

The c.20G>A (p.R7Q) alteration is located in exon 3 (coding exon 1) of the REG4 gene. This alteration results from a G to A substitution at nucleotide position 20, causing the arginine (R) at amino acid position 7 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
