| Gene |
NF1 |
| Chromosomal Location |
17q11.2 |
| Allelic Variant 1 |
162200.0001; NEUROFIBROMATOSIS, TYPE I |
| Identified Mutation |
ALU INS; Wallace et al. [Nature 353: 864 (1991)] demonstrated a de novo Alu repetitive element insertion into an intron of the NF1 gene, which resulted in deletion of the downstream exon during splicing and consequently shifted the reading frame. This previously undescribed mechanism of mutation indicated that Alu retrotransposition is an ongoing process in the human germ line. The patient was an isolated case in his family. The insertion, 300-500 bp, began 44 bp upstream of exon 6. This appears to have been the first report of a disease-causing mutation consisting of a de novo Alu insertion. |
