Familial cases with multiple cutaneous leiomyomas exist, which typically show an autosomal dominant inheritance trait. Most patients with the disease are known to carry heterozygous germ line mutations in the fumarate hydratase (<jats:italic>FH<\/jats:italic>) gene and can be complicated by tumors in internal organs, especially uterine leiomyoma and renal cell cancer in high frequency. In this study, we identified a Japanese male patient with multiple cutaneous leiomyomas and found a novel heterozygous splice site mutation, c.738\u00a0+\u00a02T&gt;A, in the <jats:italic>FH<\/jats:italic> gene of the patient, which was unexpectedly inherited from his unaffected father. Further analysis demonstrated loss of heterozygosity in the tumor tissue, which resulted in a hemizygote state of the mutant allele. Expression studies with the tumor tissue showed that the mutation led to skipping of exon 5 at mRNA levels, which was predicted to cause an in\u2010frame deletion of FH protein (p.Ser186_Gln246del). The protein structure analysis strongly suggested that the deletion would severely disrupt the conformation of the FH protein including the substrate\u2010binding domain, and thus would severely affect the expression and the function. Our findings further disclose the molecular basis of multiple cutaneous leiomyomas and also provide precious information to the mutation carriers in the family for an early diagnosis of renal cell cancer in the future.<\/jats:p>","DOI":"10.1111\/1346-8138.13019","type":"journal-article","created":{"date-parts":[[2015,7,15]],"date-time":"2015-07-15T05:21:59Z","timestamp":1436937719000},"page":"85-91","source":"Crossref","is-referenced-by-count":3,"title":["Novel
