Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_003787.5(NOL4):c.1031G>A(p.Arg344Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,578 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. R344G) has been classified as Uncertain significance.

The c.1031G>A (p.R344Q) alteration is located in exon 6 (coding exon 6) of the NOL4 gene. This alteration results from a G to A substitution at nucleotide position 1031, causing the arginine (R) at amino acid position 344 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
