Details

Cytogenetic Location: chr7 : q11.23 - q11.23
GP mRNA Boundary: chr7 : 75544420 - 75616173
GP Gene Boundary: chr7 : 75534420 - 75619173
Strand: plus
Product Name: No data available
The mRNA boundaries are calculated using the gene's default feature set from NCBI, mapped onto the UCSC Golden Path. PharmGKB sets gene boundaries by expanding the mRNA boundaries by no less than 10,000 bases upstream (5') and 3,000 bases downstream (3') to allow for potential regulatory regions.
