RCV003155866 | SCV003845132 | likely pathogenic | Usher syndrome | 2023-02-22 | criteria provided, single submitter | clinical testing | Variant summary: The variant identified by MLPA or other technology involves the deletion of exon 16 in the USH2A gene. A presumed nomenclature of c.(3157+1_3158-1)_(3316+1_3317-1)del has been designated for the purposes of this classification. Although exact breakpoints of this CNV are not known, it is expected to result in a large in-frame deletion in the USH2A gene, a known mechanism of disease. The variant was absent in 21694 control chromosomes. To our knowledge, no occurrence of c.(3157+1_3158-1)_(3316+1_3317-1)del in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
