Serum Alkaline Phosphatase (AP) values are those found at the age of diagnosis, i.e. between 6 months and 9 years of age. The normal values for children range from 123–283 UI/L.

Symbols: AR: autosomal recessive, AD: autosomal dominant

Footnote: Nucleotide and amino acid numbering are according to the international recommendation: the first nucleotide corresponds to the A of the ATG initiation codon.

The first amino acid corresponds to the ATG initiation codon.
