Nf. Box et al., COMPLETE SEQUENCE AND POLYMORPHISM STUDY OF THE HUMAN TYRP1 GENE ENCODING TYROSINASE-RELATED PROTEIN-1, Mammalian genome, 9(1), 1998, pp. 50-53
The complete 24,667 nucleotide sequence spanning the human TYRP1 gene
has been determined from the inserts of two overlapping lambda clones.
A LINE-1 repeat element is immediately adjacent to and may demarcate
the immediate 5' promoter region of the gene. A search for polymorphis
m within the seven TYRP1 coding exons has been performed by an RNase m
ismatch detection procedure. Analysis of the TYRP1 gene in 100 Caucasi
an individuals of varying hair color has found no amino acid sequence
variation nor revealed any hemizygous mutant allele in the hypopigment
ed phenotype of two 9p(-) syndrome patients.
