Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4_ModerateBS2

The NM_001142966.3(GREB1L):c.203G>T(p.Arg68Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000143 in 1,551,274 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R68H) has been classified as Uncertain significance.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), GREB1L. . Gene score misZ 5.3659 (greater than the threshold 3.09). Trascript score misZ 5.6738 (greater than threshold 3.09). GenCC has associacion of gene with bilateral renal agenesis, renal hypodysplasia/aplasia 3, renal agenesis, unilateral, hearing loss, autosomal dominant 80.

BP4

Computational evidence support a benign effect (MetaRNN=0.15200263).

BS2

High AC in GnomAd4 at 19 AD gene.

The GREB1L c.203G>T variant is predicted to result in the amino acid substitution p.Arg68Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.021% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/18-18964212-G-T). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
