Invitae RCV000560155 SCV000650870 uncertain significance Atrial standstill 1; Atrial fibrillation, familial, 11 2018-04-23 criteria provided, single submitter clinical testing A gross duplication of the genomic region encompassing the full coding sequence of the GJA5 gene has been identified. The boundaries of this event are unknown as the duplication extends beyond the assayed region for this gene and therefore may encompass additional genes. As the precise location of this duplication is unknown, it may be in tandem or it may be located elsewhere in the genome. Isolated whole-gene duplications of GJA5 have not been reported in the literature. However, larger copy number events that include this gene have been reported in individuals with congenital heart disease among other variable clinical features (PMID: 22199024, 22912587, 25205790, 26279651, 27930557). In summary, the exact genomic location of this variant is unknown and the impact of this duplication on GJA5 protein function has not been established. Therefore, it has been classified as a Variant of Uncertain Significance.
