Description

This CNV is a 1.87 Mb deletion of 5q35.2q35.3 on chromosome 5, (seq[GRCh37]del(5)(q35.2q35.3);NC_000005.9:g.175559209_ 177430432del), that occurred de novo. This event is located near the q terminus of chromosome 5 but does not extend to the telomere. This CNV encompasses 38 protein coding genes, including NSD1, DDX41, and SLC34A1. Haploinsufficiency of NSD1 is a known cause of Sotos syndrome (PMID: 11896389; 17565729; 20301652; 23190751). Microdeletions of 5q35.2q35.3 involving NSD1 have been especially frequently observed in Japanese patients with Sotos syndrome (PMID: 14517949; 20301652). Similar CNVs have not been reported in controls (PMID: 21841781; 24174537). This CNV also encompasses the DDX41 gene, haploinsufficiency of which is associated with DDX41-related hematologic malignancy predisposition syndrome. Based on the available evidence, this CNV is classified as pathogenic.
