A Novel Intronic Splicing Mutation in the EXT2 Gene of a Chinese Family with Multiple Osteochondroma.

Abstract excerpt

Background: Multiple osteochondroma (MO), an autosomal dominant genetic disease, is caused by heterozygous mutations in the EXT1 and EXT2 genes. Approximately 80% of pathogenic mutations are nonsense/missense mutations, small indels, and splicing mutations. Splicing mutations, particularly at the 3' and 5' splice sites, disrupt normal mRNA processing and cause exon skipping or aberrant splicing, ultimately...
