Overview
Familial hypocalciuric hypercalcemia is classified into three types. Type-1 is due to loss-of-function mutations of the calcium-sensing receptor, type-2 is caused by the mutation of GNA 11 gene, type-3 is associated with adaptor-related protein complex 2, sigma 1 subunit (AP2S1) mutations, which alter the endocytosis of calcium-sensing receptor.
Classification
Classification based on genetic mutations
FHH is an autosomal dominantt benign inherited condition caused by three types of mutations the most common mutation is an inactivating missense mutation of the CASR located on chromosome 3q. It may be very rarely is caused by the mutation of GNA11 gene and AP2S1 gene.[1][2]
There are three types of FHH:
- Type-1: caused by loss-of-function mutations of the calcium-sensing receptor (CaSR), a G-protein coupled receptor that predominantly signals via G-protein subunit alpha-11 (Gα11) to regulate calcium homeostasis located on chromosome 3q13.3-q21.[3][4]
- Type-2: caused by heterozygous mutation in the GNA11 gene on chromosome 19p13.[5]
- Type-3: caused by heterozygous mutation in the AP2S1 gene on chromosome 19q13.[6][7]
