ABSTRACT
<p><b>OBJECTIVE</b>To screen for mutations of NTRK1 gene in a Chinese family affected with congenital insensitivity to pain with anhidrosis (CIPA).</p><p><b>METHODS</b>Genomic DNA was extracted from the proband and her family members. All of the 17 exons and intron-exon boundaries of the NTRK1 gene were analyzed by direct Sanger sequencing. For the deletional mutation, the PCR products were subjected to T-A cloning and sequencing to verify the mutation.</p><p><b>RESULTS</b>NTRK1 gene analysis revealed that proband has carried a c.1786C>T (p.Arg596*) nonsense mutation inherited from her mother and a novel deletional mutation c.1928-2028+23del from her father. Her elder brother only carried the deletional mutation.</p><p><b>CONCLUSION</b>The diagnosis of CIPA relied on typical clinical symptoms of no pain, anhidrosis and intellectual disability and detection of the biallelic NTRK1 mutations. The novel deletional mutation has enriched the spectrum of NTRK1 mutations.</p>
