Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 3P and 2B. PM2 PP2 BP4_Moderate

The NM_130847.3(AMOTL1):​c.277G>C​(p.Ala93Pro) variant causes a missense change. The variant allele was found at a frequency of 0.000000686 in 1,457,542 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A93S) has been classified as Uncertain significance.

Genes affected

AMOTL1 (HGNC:17811): (angiomotin like 1) The protein encoded by this gene is a peripheral membrane protein that is a component of tight junctions or TJs. TJs form an apical junctional structure and act to control paracellular permeability and maintain cell polarity. This protein is related to angiomotin, an angiostatin binding protein that regulates endothelial cell migration and capillary formation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

AMOTL1 Gene-Disease associations (from GenCC):

• orofacial cleft

  Inheritance: AD Classification: MODERATE Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• 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: 1.2216 (below the threshold of 3.09). Trascript score misZ: 1.2775 (below the threshold of 3.09). GenCC associations: The gene is linked to orofacial cleft.
• BP4: Computational evidence support a benign effect (MetaRNN=0.21983632).
