Molecular genetic characterization of a Korean split hand/split foot malformation (SHFM).

Split hand/split foot malformation (SHFM; ectrodactyly) is genetically heterogeneous, with mutations identified at five loci (SHFM1 at 7q21.3, SHFM2 at Xq26, SHFM3 at 10q24, SHFM4 at 3q27 and SHFM5 at 2q31). In this study, we attempted to identify and localize the causative allele of a Korean case of SHFM.

Identification of enteroviruses by using monoclonal antibodies against a putative common epitope.

A common epitope region of enteroviruses was identified by sequence-independent single-primer amplification (SISPA), followed by immunoscreening of 11 cDNA libraries from two Korean enterovirus isolates (echoviruses 7 and 30) and a coxsackievirus B3 (ATCC-VR 30). The putative common epitope region was localized in the N terminus of VP1 when the displayed recombinant proteins from the phages were chased by the convalescent-phase sera. The genomic region encoding the common epitope region was amplified and then expressed by using the vector pGEX-5X-1.
