Labcorp Genetics (formerly Invitae), Labcorp RCV000810000 SCV000950186 uncertain significance Epilepsy, childhood absence, susceptibility to, 1; Epilepsy, childhood absence, susceptibility to, 5 2019-01-04 criteria provided, single submitter clinical testing This variant results in a copy number gain of the genomic region encompassing the full coding sequence of the GABRB3 gene. The boundaries of this event are unknown as they extend beyond the assayed region for this gene and therefore may encompass additional genes. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. While a whole-gene copy number gain of just the GABRB3 gene alone has not been reported in the literature, much larger copy number variants encompassing more than 5 Mb of DNA (15q11-q13) and multiple adjacent genes have been reported in individuals with a wide spectrum of neuropsychiatric disorders (PMID: 26068938, 23495136, 28281572). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
