The Tissue Nonspecific Alkaline Phosphatase
Gene Mutations Database

Welcome to the ALPL gene mutations database. This site has been compiled to provide up-to-date information about genetic variation of the ALPL gene responsible for hypophosphatasia.

The database has been initiated by the SESEP Laboratory (now integrated in Versailles Hospital as the Unit of Constitutional Genetics) and the Unit of Cell and Genetics Pathology (EA2493) of the University of Versailles-Saint Quentin en Yvelines, France.

Hypophosphatasia (MIM 146300, 241500, 241510)

Hypophosphatasia is a rare inherited disorder characterized by defective bone and teeth mineralization and deficiency of serum and bone alkaline phosphatase activity. For severe forms, the prevalence of the disease has been estimated to 1/300,000 in Europe and 1/100 000 in Canada. The symptoms are highly variable in their clinical expression, which ranges from stillbirth without mineralized bone to early loss of tooth without bone symptoms (Whyte 1994). The transmission of severe forms is autosomal recessive while milder forms may be transmitted as dominant or recessive autosomal traits. The disease is due to mutations in the alkaline phosphatase liver-type (ALPL) gene, also named the TNSALP gene. See more informations in Orphanet.

The ALPL gene (ID:249; MIM 171760), localized on chromosome 1p36-34 (Greenberg et al. 1990), consists of 12 exons distributed over 50 kb (Weiss et al. 1988) and is subject to very strong allelic heterogeneity. To date, at least 300 distinct mutations are known (see the list of mutations below and the list of polymorphisms). The patients examined mostly consisted of European, North-American, Australian and Japanese individuals.

Legend to database items

Nomenclature : see the nomenclature section below.
Reference : reference of the publication reporting the mutation.
Clinical form : clinical form of the patient in whom the mutation was detected for the first time.
Genotype : genotype of the patient in whom the mutation was detected for the first time.
? : uncharacterized allele (only one detected mutation without molecular, pedigree, or in silico evidence of dominant transmission).
N : normal allele (dominant mutation on the other chromosome, evidenced by molecular, pedigree, or in silico data.
%WT : alkaline phosphatase activity of cells transfected with mutated cDNAs, expressed in percentage of the activity found in cells transfected with wild type (WT) cDNA.
ref : reference reporting transfections experiments.
unp. : unpublished.
Conservation : conservation of the affected amino acid among 58 mammalian TNSALP according to Silvent et al. (2014). ++ conserved residue ; + conservative changes only, - residue not conserved, na not applicable.

Nomenclature

Nucleotides numbering is given according to Weiss et al. 1988, the Nomenclature Working Group (S.E. Antonarakis and the Nomenclature Working Group, Hum. Mut. 11:1-3, 1998) and the HGVS recommendations: the first nucleotide (+1) corresponds to the A of the ATG initiation codon. The reference cDNA sequence is NM_000478.4

Amino acids numbering is given according to both the standardized and the non-standardized nomenclatures.
The standardized nomenclature follows the HGVS recommendations: the first codon is the ATG initiation codon.
The non-standardized nomenclature was used in publications before 2008-2009 : this nomenclature takes into account of a 17-residues signal peptide, i.e. the ATG initiation codon is numbered as residue minus (-)17 (Weiss et al. 1988). The reference cDNA sequence is NM_000478.4

p: protein numbering; c: nucleotide numbering of the coding sequence.
