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]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.805
• PP5: Variant 11-94799659-C-T is Pathogenic according to our data. Variant chr11-94799659-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 2750552.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 157 of the AMOTL1 protein (p.Arg157Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with AMOTL1-related conditions (PMID: 30375152, 36116699; Invitae). In at least one individual the variant was observed to be de novo. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. -
