We report a new case with similar features and a novel variant in <jats:italic>YY1<\/jats:italic>, in a region of the gene, which has not previously been reported. A 25\u2009year old female was referred to clinical genetics with a diagnosis of autoimmune myasthenia gravis, facial dysmorphism and learning disability. Chromosomal microarray and gene panel test for congenital myasthenic syndrome was negative. Whole exome sequencing (WES) revealed a presumed pathogenic de novo novel, heterozygous, truncating variant in the <jats:italic>YY1<\/jats:italic> gene, c.860_864delTTAAAA, p.Ile287Argfs*3. The Ile287 residue is conserved across species and is situated in the transcription repressor domain of the protein. This variant is novel and lies in a domain of the protein where no previously reported variants occur. The phenotypic features of our case closely match those of the reported patients. Autoimmune myasthenia gravis has not been reported in these patients and may constitute an expansion of this phenotypic spectrum or perhaps more likely a second unrelated diagnosis.<\/jats:p>","DOI":"10.1002\/ajmg.a.40626","type":"journal-article","created":{"date-parts":[[2018,12,14]],"date-time":"2018-12-14T11:26:44Z","timestamp":1544786804000},"page":"2846-2849","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["A
