Mcoln3^Va-J

This allele has a T-to-C transition at coding nucleotide 1085 within exon 8. This results in a change from isoleucine to threonine at amino acid 362 (p.I362T) in the second extracellular loop. The Mcoln3Va-J allele, which arose on a strain segregating for the more severe Mcoln3Va allele, also has the G-to-C transversion at coding nucleotide 1255 (p.A419P) specific to the Mcoln3Va allele indicating that the Mcoln3Va-J allele contains an additional point mutation to the Mcoln3Va allele. The less severe phenotype of the Mcoln3Va-J allele suggests that the T-to-C transition at nucleotide 1085 might mitigate the effects of the G-to-C mutation at nucleotide 1255 although the impact of genetic background must be considered. The encoded protein can be detected in the hair cells of heterozygous and homozygous mice. (J:80336)
