ABSTRACT
OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with split hand/foot malformation (SHFM).@*METHODS@#Genomic DNA of the proband and other affected members was extracted from peripheral blood samples. Chromosomal microarray analysis was employed to detect genome-wide copy number variations (CNVs).@*RESULTS@#A 400 kb microduplication was identified in the 10q24.31-q24.32 region among all affected individuals. The microduplication has involved four genes, namely LBX1, BTRC, POLL and DPCD, in addition with part of FBXW4 gene.@*CONCLUSION@#The 10q24.31-q24.32 microduplication has segregated with the disease phenotype in this pedigree and probably underlay the SHFM malformation in the patients.
