ABSTRACT
<p><b>OBJECTIVE</b>To determine the molecular etiology for a family affected with autosomal dominant polycystic kidney disease and provide prenatal diagnosis for the family.</p><p><b>METHODS</b>Clinical data of the family was collected. Target region sequencing with monogenetic disorders capture array combined with Sanger sequencing and bioinformatics analysis were performed in turn. SIFT and NCB1 were used to evaluate the conservation of the gene and pathogenicity of the identified mutation.</p><p><b>RESULTS</b>Target region sequencing has identified a novel c.11333C to A (p.T3778N) mutation of the PKD1 gene in the proband and the fetus, which was confirmed by Sanger sequencing in three affected individuals from the family. The same mutation was not detected in healthy members of the pedigree. Bioinformatics analysis suggested that the mutation has caused a likely pathogenic amino acid substitution of Threonine by Aspartic acid, and Clustal analysis indicated that the altered amino acid is highly conserved in mammals.</p><p><b>CONCLUSION</b>A novel mutation of the PKD1 gene has been identified in an affected Chinese family. The mutation is probably responsible for a range of clinical manifestations, for which reliable prenatal diagnosis and genetic counseling may be provided.</p>
