Description

This variant results in a copy number gain of the genomic region encompassing exons 1-7 of the DNM2 gene. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 7 of the DNM2 gene. As the precise location of this event is unknown, it may be in tandem or it may be located elsewhere in the genome. This variant has not been reported in the literature in individuals with DNM2-related disease. Experimental studies are not available for this variant, and the functional significance of a copy number gain of these exons is currently unknown. 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.
