Variant summary

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

The NM_203304.4(MEX3D):​c.1571G>T​(p.Arg524Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000111 in 1,171,640 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 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. R524C) has been classified as Uncertain significance.

The c.1571G>T (p.R524L) alteration is located in exon 2 (coding exon 2) of the MEX3D gene. This alteration results from a G to T substitution at nucleotide position 1571, causing the arginine (R) at amino acid position 524 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
