The woolly mutation comprises a T to C transition at nucleotide position 87975 of the genomic DNA sequence (Genbank genomic region NC_000067 for linear genomic DNA sequence of Sgk3), in the 16th of the gene's 19 exons. The mutated base corresponds to nucleotide 1382 of transcript variant 1, Genbank record: NM_133220. The mutation is predicted to result in replacement of the cysteine at amino acid position 246, in the kinase domain, by arginine (C246R). (J:156584)
