ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2

Missense variant in the GREB1L gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 17 curated pathogenic missense variants (we use a threshold of 10). The gene has 23 curated benign missense variants. Gene score misZ: 5.3659 (above the threshold of 3.09). Trascript score misZ: 5.6738 (above the threshold of 3.09). GenCC associations: The gene is linked to 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).

BP6

Variant 18-21384251-G-T is Benign according to our data. Variant chr18-21384251-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 2432267.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1}.

BS2

High AC in GnomAd4 at 19 AD gene.

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

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. -
