Fig. 5From: Recurrent myocardial injury in a de novo SON mutation ZTTK syndrome patient: a case reportSON mutation was confirmed by Sanger sequencing in the patient and her parents. The patient was found to have a heterozygous mutation, c.3852_3856delGGTAT (p.Met1284Ilefs*2), in exon 3 of the SON gene (indicated by the red arrow in Fig. 3). This mutation was determined to be de novo, meaning it was not inherited from the patient’s parentsBack to article page
