This spontaneous mutation in chromosome 6 has a G-to-A transition at 91,394,552 (GRCm38) causing the replacement of arginine with tryptophan at amino acid 143 (p.R143W), and also has a 23,106 bp intragenic deletion, 91,371,385-91,394,492, that encompasses a portion of exon 3 and removes the 5' end of intron 3 including the splice donor site.
