Criteria Specification Information

Criteria Specifications for this VCEP
Evidence submitted by expert panel
Rett and Angelman-like Disorders VCEP
The variant has been reported to segregate in at least five informative meioses (PMID 25212744, internal database) (PP1_Strong). A pathogenic missense variant (p.Thr106Pro) has been previously identified within this codon which indicates that this residue is critical to the function of the protein (PMID 15054837) (PM5). Protein expression analysis in transfected cell lines has shown that this variant reduces protein function (PMID 26255772) PS3_Supporting). The p.Thr106Lys variant has been observed in at least 1 other individual with Angelman syndrome (PMID 25212744) (PS4_Supporting). The p.Thr106Lys variant in UBE3A is absent from gnomAD (PM2_Supporting). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). In summary, the p.Thr106Lys variant in UBE3A is classified as pathogenic for Angelman syndrome based on the ACMG/AMP criteria (PP1_strong, PM5, PS3_supporting, PS4_supporting, PM2_supporting, PP3).
