BTD Database

• Reference sequences were NC_000003.10 and NM_000060.2. cDNA number 1 is the "A" of the start codon.
• Frameshift is documented by the original amino acid followed by the codon number and "fs" (ex. Leu159 fs).
• Click any Column Header to sort the display. Mouse over Comments icon for additional details.
• "Live Search" any term in the search box, such as "exon" , "missense", "benign" , etc...
• Due to instability of the biotinidase enzyme, ARUP and other laboratories require samples submitted for biotinidase activity testing be accompanied by a paired control drawn at the same time as the patient. This paired control should be collected from a normal, healthy individual who is not biologically related to the patient. ARUP's normal reference range for this assay is 3.5-13.8 U/L.
