ABSTRACT
<p><b>OBJECTIVE</b>To identify potential mutation of COL1A1 gene in an ethnic Han Chinese family from Henan affected with osteogenesis imperfecta (OI).</p><p><b>METHODS</b>Peripheral blood samples were collected from all 11 members of the family and 50 healthy adults for the extraction of genomic DNA. All exons and introns of the COL1A1 gene were amplified by polymerase chain reaction and subjected to direct sequencing. Mutations found in the proband were analyzed through comparison with other members of the family, 50 healthy individuals and sequence from the GenBank.</p><p><b>RESULTS</b>Fifteen sequence variants were discovered, which included 1 missense mutation, 1 synonymous mutation and 13 intronic mutations. All of the 4 patients from the family were detected as having carried a novel heterozygous missense mutation (c.4193T>G, p.I1398S) in exon 50 of the COL1A1 gene. The father of the proband has carried the same mutation but had a normal phenotype. The same mutation was not found in other healthy members of the family.</p><p><b>CONCLUSION</b>The OI type of this family may have been autosomal dominant with incomplete penetrance or autosomal recessive associated with COL1A1 gene mutations.</p>
