191315.0002; INSENSITIVITY TO PAIN, CONGENITAL, WITH ANHIDROSIS |
| Identified Mutation |
IVSDS A-C, +3; In 2 Ecuadorian brothers with congenital insensitivity to pain with anhidrosis (GM08382 and GM08383), Indo et al. (1996) found a deletion of exon D (nucleotides 1872-2112) on 1 allele of the NTRK1 gene. Part of the same exon (nucleotides 1966-2112) was deleted on the other allele, indicating the presence of RNA splicing errors. The partial exon deletion was apparently due to activation of a cryptic splice donor site. Sequencing of genomic DNA revealed that the 5-prime splice site of an intron between exons D and E contained an A-to-C transversion in the third position. Such mutations are known to result in skipping of the preceding exon. No substitution was found in exon D and the flanking exon/intron junctions. Restriction digestion analysis demonstrated that GM08382 and GM08383 (identification numbers for cell lines in the NIGMS cell bank) were homozygous for the A-to-C transversion and that the parents were heterozygous.
