| Is Wild Type | false |
| molecularNote | The mutation in the bald Mill Hill mouse was determined to be a small 296 bp deletion of genomic DNA that includes part of exon 19 and the 3' UTR of the gene. The mutant allele is expressed in a similar pattern to the wild-type message. However the resulting protein is 150 rather than 130 kDa in size. |
