“…The latter considers sequence and copy number variants without any transcriptomic or epigenetic research [ 4 ]. The likelihood of finding a specific genetic diagnosis with the current approach has ranged between 7 and 60 % [ 40 , 41 ]. Our results highlight the importance of considering mechanisms beyond specific DNA changes involved in expression anomalies of SOX9 , such as epigenetic markers, which are not currently included in the diagnostic evaluation.…”
