HCM is characterized as left ventricular hypertrophy in the absence of any other loading conditions. In previous studies, mutations in at least 50 genes have been identified in HCM patients.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_cclm-2018-0578_s_998_w2aab3b7c70b1b6b1aab1c17b2Aa\">\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>In this research, the genetic lesion of an HCM patient was identified by whole exome sequencing.

We then generated HIS-<jats:italic>SMYD1<\/jats:italic>-pcDNA3.1+ (WT and c.814T&gt;C\/p.F272L) plasmids for transfection into AC16 cells to functionalize the mutation. The immunofluorescence experiments indicated that this mutation may block the SMYD1 protein from entering the nucleus. Both Western blot and real-time PCR revealed that, compared with cells transfected with WT plasmids, the expression of HCM-associated genes such as \u03b2-myosin heavy chains, SMYD1 chaperones (HSP90) and downstream targets including TGF-\u03b2 were all disrupted in cells transfected with the mutant plasmid. Previous studies have demonstrated that SMYD1 plays a crucial role in sarcomere organization and heart development.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"j_cclm-2018-0578_s_996_w2aab3b7c70b1b6b1aab1c17b4Aa\">\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>This novel mutation (c.814T&gt;C\/p.F272L) may be the first identified disease-causing mutation of <jats:italic>SMYD1<\/jats:italic> in HCM patients worldwide.
