Invitae RCV000628547 SCV000749449 pathogenic Beckwith-Wiedemann syndrome 2017-11-22 criteria provided, single submitter clinical testing This sequence change replaces arginine with tryptophan at codon 2017 of the NSD1 protein (p.Arg2017Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is not present in population databases (ExAC no frequency). This variant has been reported in several individuals affected with Sotos syndrome being found to be de novo in at least two of them (PMID: 12807965, 15942875, 26690673). ClinVar contains an entry for this variant (Variation ID: 159397). Experimental studies have shown that this missense change abolishes enzyme NSD1 activity in vitro (PMID: 24412544). For these reasons, this variant has been classified as Pathogenic.
