Unique mutation code number. Activating mutation number preceded by A. Inactivating mutation number preceded by I.

Nucleotide change:

"c." designates the nucleotide relative to c.1 that is the A in the ATG of the initiation codon. Note c. number preceded by a minus sign, e.g., c.-10 designates the nucleotide 10 -bp upstream in the part of the gene encoding the 5' untranslated region of the mRNA.

Mutation trivial name:

Amino acid change, e.g., G269S, the notation consists of the normal amino acid (one-letter code) followed by the codon number and the mutant amino acid. Intronic mutation, e.g., IVS2+1g>a, the notation consists of IVS followed by intron number, then position in the intron (can be + or -), then the original nucleotide and the mutant nucleotide. Deletion or insertion, e.g., c. 547.insA, the notation consists of "c" preceded and followed by a period), then ins or del and finally the nucleotide(s) that are inserted or deleted.

Region affected:

E1-E7, exons 1-7; IVS, intervening sequence; 5'UTR, 5' untranslated region; SP, signal peptide; ECD, extracellular domain; TM1-7, transmembrane helices 1-7; ICL1-3, intracellular loops 1-3; ECL1-3, extracellular loops 1-3, ICD, intracellular domain.

Nucleotide start:
Nucleotide stop:

Precise placement of the mutation.

Type of mutation:

Missense, nonsense (protein coding), nucleotide change(s) if in an untranslated region (mRNA) or intervening sequence (gene).

Disease: Activating

ADH, autosomal dominant hypocalcemia; IE, idiopathic epilepsy; IH, idiopathic hypercalciuria; Poly, polymorphism.

Disease: Inactivating

FHH, familial hypocalciuric hypercalcemia; NSHPT, neonatal severe hyperparathyroidism; FHH/NSHPT, expression in a kindred of FHH or NSHPT affected members; FIHP, familial isolated hyperparathyroidism; TCP, tropical chronic pancreatitis; Poly, polymorphism.
