    Description

    This CNV is a 96 Mb gain of 13q12q34 on chromosome 13, (seq[GRCh37]dup(13)(q12q34);chr13:g.19253848_115108937dup). This gain encompasses 314 protein coding genes and is consistent with trisomy of the long arm of chromosome 13 (trisomy 13q). Gains of 13q only are described in up to 20% of individuals with various forms of trisomy 13, and are typically associated with de novo or inherited structural chromosome rearrangements including Robertsonian translocations or isochromosomes (Noriega and Siddik 2021). This CNV has not been reported in controls. Based on the available evidence, this CNV is classified as pathogenic.
