Erratum

This article refers to:

Serum free and bio-available 25-hydroxyvitamin D correlate better with bone density than serum total 25-hydroxyvitamin D

Johnsen MS, Grimnes G, Figenschau Y, Torjesen PA, Almås B, Jorde R. Serum free and bio-available 25-hydroxyvitamin D correlate better with bone density than serum total 25-hydroxyvitamin D. Scand J Clin Lab Invest. 2014;74(3):177-83.

On page 3 of this paper there is in the left hand column a table with Diplotype, Phenotype and Binding coefficient.

Unfortunately, the order of the binding coefficients in that column was incorrect. The correct version is given below. However, in all calculations the correct binding coefficients were used, and all results are as appears in the article.

Table

Diplotype	Phenotype	Binding coefficient
GC/GC	Gc-1S/Gc-1S	6 × 10^8
GC/TC	Gc-1S/Gc-1F	8.6 × 10^8
GC/TA	Gc-1S/Gc-2	4.8 × 10^8
TC/TC	Gc-1F/Gc-1F	11.2 × 10^8
TC/TA	Gc-1F/Gc-2	7.4 × 10^8
TA/TA	Gc-2/Gc-2	3.6 × 10^8
