Abstract:
OBJECTIVETo detect the mutation of the SEDL gene in an X-linked spondyloepiphyseal dysplasia tarda (SEDL) family.
METHODSTwo patients and three females of the X-SEDL family were detected using reverse transcriptase PCR (RT-PCR) and sequence analysis.
RESULTSA G209A mutation of SEDL gene was detected in the cDNA sequences of the patients, which was confirmed by sequence analysis of the exon 4 of the SEDL gene. The daughter of the proband was a carrier of the mutation.
CONCLUSIONSince the SEDL gene is relatively small, sequence analysis of cDNA of the SEDL gene was possible after extraction of total RNA followed by RT-PCR. Mutations in the open reading frame can be detected y by cDNA sequencing. It was relatively more rapid and direct than amplifying and detecting the exons one by one.
