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: Uncertain_significance. The variant received 5 ACMG points.

PM1

In a mutagenesis_site Decreased VASH1 tyrosine carboxypeptidase activity on alpha-tubulin. (size 0) in uniprot entity SVBP_HUMAN

PM2

Very rare variant in population databases, with high coverage;

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.

The c.104A>G (p.Q35R) alteration is located in exon 2 (coding exon 1) of the SVBP gene. This alteration results from a A to G substitution at nucleotide position 104, causing the glutamine (Q) at amino acid position 35 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
