This report is of a 6-month-old male infant with typical symptoms and signs of congenital insensitivity to pain with anhidrosis. He had a homozygous insertion mutation with c.2086-2087 ins C of neurotrophic tyrosine kinase receptor type 1 (NTRK1) gene with both parents as heterozygous carriers. This mutation may have a strong relation to hereditary sensory and autonomic neuropathy type IV Taiwanese patients. This is the youngest reported patient in Taiwan and first reported with congenital insensitivity to pain with mutation of NTRK1 gene inherited from the parents. Early diagnosis may provide appropriate medical care and education for these children and their families for better prognosis. ? 2010 The Author(s).[SDGs]SDG3neurotrophic tyrosine kinase receptor 1; protein tyrosine kinase; unclassified drug; anhidrosis; article; clinical article; clinical feature; congenital analgesia; congenital insensitivity to pain with anhidrosis; gene insertion; gene mutation; heterozygosity; human; infant; laboratory test; male; neurologic examination; physical examination; priority journal; Taiwan; Age of Onset; Asian Continental Ancestry Group; DNA Mutational Analysis; Genetic Predisposition to Disease; Genetic Testing; Genotype; Hereditary Sensory and Autonomic Neuropathies; Humans; Infant; Male; Mutation; Receptor, trkA; Taiwanjournal article10.1177/0883073810375464206475792-s2.0-78650191486
