Genomic DNA was isolated from peripheral blood lymphocytes of a patient with familial amyloidotic polyneuropathy (FAP) and the transthyretin (TTR) gene examined for sequence mutations. Polymerase chain reaction was used to asymmetrically amplify the TTR exons. Direct DNA sequencing of the PCR product revealed a C for T mutation at the first base of codon 33 located in exon 2 of one transthyretin gene. This resulted in a substitution of leucine for phenylalanine at position 33. Exons 3 and 4 were examined and found to be normal. The mutation creates a novel DdeI restriction site at the point of the mutation.

D009477 Hereditary Sensory and Autonomic Neuropathies A group of inherited disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and clinically by loss of sensation and autonomic dysfunction. There are five subtypes. Type I features autosomal dominant inheritance and distal sensory involvement. Type II is characterized by autosomal inheritance and distal and proximal sensory loss. Type III is DYSAUTONOMIA, FAMILIAL. Type IV features insensitivity to pain, heat intolerance, and mental deficiency. Type V is characterized by a selective loss of pain with intact light touch and vibratory sensation.
