Genes affected

SVBP (HGNC:29204): (small vasohibin binding protein) Enables microtubule binding activity. Involved in axon development; proteolysis; and regulation of metallopeptidase activity. Acts upstream of or within negative regulation of endothelial cell migration; negative regulation of protein ubiquitination; and protein secretion. Located in apical part of cell.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.3744 (below the threshold of 3.09). Trascript score misZ: 0.51921 (below the threshold of 3.09). GenCC associations: The gene is linked to syndromic intellectual disability.

BP4

Computational evidence support a benign effect (MetaRNN=0.27897364).

BS2

High AC in GnomAd4 at 9 AD gene.

The c.91C>G (p.L31V) alteration is located in exon 2 (coding exon 1) of the SVBP gene. This alteration results from a C to G substitution at nucleotide position 91, causing the leucine (L) at amino acid position 31 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
