    Description

    A confirmed de novo heterozygous deletion of 15q11.2-12 encompassing 22 genes (https://genescout.omim.org/) was identified by exome sequencing and confirmed by qPCR in one individual with Angelman syndrome ([GRCh38] chr15:20966971_25963714x1). These breakpoints have been estimated by qPCR and therefore may not reflect the true breakpoints. The patient phenotype is nonspecific, but is consistent with cases described in the literature and/or published databases with overlapping variants. There is complete overlap with the UBE3A gene which is known to be haploinsufficient and has been assessed by the ClinGen Dosage Sensitivity Working Group (https://search.clinicalgenome.org/kb/gene-dosage). In summary, the 15q11.2-12 deletion meets criteria to be classified as pathogenic. The ACMG/ClinGen evidence codes and points used in this curation are as follows: 1: 0 points, 2: 1.00 points, 3: 0 points, 4-5: 0.15 points; Total: 1.15 points; Riggs 2020 (PMID: 31690835)
