This spontaneous mutation is the minor variant of SNP rs221612964 that lacks the A in the TATT sequence, resulting in TTT in exon 2. This results in a non-functional gene that is found only in the C57BL/6 strain. All other 16 strains tested have the TATT sequence which yields a functional gene. (J:291240)
