Genes affected

AMOT (HGNC:17810): (angiomotin) This gene belongs to the motin family of angiostatin binding proteins characterized by conserved coiled-coil domains and C-terminal PDZ binding motifs. The encoded protein is expressed predominantly in endothelial cells of capillaries as well as larger vessels of the placenta where it may mediate the inhibitory effect of angiostatin on tube formation and the migration of endothelial cells toward growth factors during the formation of new blood vessels. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• PP5: Variant X-112791832-C-G is Pathogenic according to our data. Variant chrX-112791832-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 224811.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-112791832-C-G is described in Lovd as [Likely_pathogenic].
