The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant is present in population databases (rs121909092, ExAC 0.006%). This variant has been reported repeatedly in the literature in individuals affected with autosomal dominant centronuclear myopathy (PMID: 22613877, 25501959, 25262827, 20927630, 22396310, 23338057, 20227276, 17008356, 24465259, 21221624, 19130742).  It is considered one of the most common mutations causing this disorder and has been shown to arise de novo in numerous affected individuals (PMID: 16227997, 25957634, 23338057, 26273216, 22396310, 23394783).  ClinVar contains an entry for this variant (Variation ID: 7282) Experimental studies have shown that this variant causes an increase in GTPase activity of the dynamin-2 protein along and formation of oligomers that are resistant to disassembly (PMID: 20529869). Additionally this variant has been shown to have a dominant negative effect on dynamin-2 protein function (PMID: 26199319, 21762456). For these reasons, this variant has been classified as Pathogenic.
