Gene screening in five Chinese families with hereditary spastic paraplegia with thin corpus callosum / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To screen all ten genes between D15S971 and D15S1012 in five Chinese families with hereditary spastic paraplegia with thin corpus callosum (HSP-TCC).</p><p><b>METHODS</b>DNA samples from 5 HSP-TCC families were screened for mutations in AK128197, MGC14798, HH114, MEIS2, MGC35118, SPRED1, AK128458, FLJ38426, RASGRP1 and AK093014 on chromosome 15q13-15 between microsatellites D15S971 and D15S1012 by polymerase chain reaction, direct sequencing and cosegreagation analysis.</p><p><b>RESULTS</b>No disease-causing mutations were found in the 10 genes, but 13 polymorphisms were identified in which two were novel.</p><p><b>CONCLUSION</b>This study did not support the ten genes between D15S971 and D15S1012 were the disease-causing genes of the 5 HSP-TCC families.</p>
