The ANK repeat region mediates interaction with Ca(2+)-calmodulin and ATP binding (By similarity). The ANK repeat region mediates interaction with phosphatidylinositol-4,5-bisphosphate and related phosphatidylinositides (PubMed:25256292).
Non-selective calcium permeant cation channel involved in osmotic sensitivity and mechanosensitivity (PubMed:16293632, PubMed:18695040, PubMed:18826956, PubMed:22526352, PubMed:23136043, PubMed:29899501). Activation by exposure to hypotonicity within the physiological range exhibits an outward rectification (PubMed:18695040, PubMed:18826956, PubMed:29899501). Also activated by heat, low pH, citrate and phorbol esters (PubMed:16293632, PubMed:18695040, PubMed:18826956, PubMed:20037586, PubMed:21964574, PubMed:25256292). Increase of intracellular Ca(2+) potentiates currents. Channel activity seems to be regulated by a calmodulin-dependent mechanism with a negative feedback mechanism (PubMed:12724311, PubMed:18826956). Promotes cell-cell junction formation in skin keratinocytes and plays an important role in the formation and/or maintenance of functional intercellular barriers (By similarity). Acts as a regulator of intracellular Ca(2+) in synoviocytes (PubMed:19759329). Plays an obligatory role as a molecular component in the nonselective cation channel activation induced by 4-alpha-phorbol 12,13-didecanoate and hypotonic stimulation in synoviocytes and also regulates production of IL-8 (PubMed:19759329). Together with PKD2, forms mechano- and thermosensitive channels in cilium (PubMed:18695040). Negatively regulates expression of PPARGC1A, UCP1, oxidative metabolism and respiration in adipocytes (By similarity). Regulates expression of chemokines and cytokines related to pro-inflammatory pathway in adipocytes (By similarity). Together with AQP5, controls regulatory volume decrease in salivary epithelial cells (By similarity). Required for normal development and maintenance of bone and cartilage (PubMed:26249260). In its inactive state, may sequester DDX3X at the plasma membrane. When activated, the interaction between both proteins is affected and DDX3X relocalizes to the nucleus (PubMed:29899501). In neurons of the central nervous system, could play a role in triggering voluntary water intake in response to increased sodium concentration in body fluid (By similarity).

Brachyolmia 3
BCYM3
A form of brachyolmia, a clinically and genetically heterogeneous skeletal dysplasia primarily affecting the spine and characterized by a short trunk, short stature, and platyspondyly. BCYM3 is an autosomal dominant form with severe scoliosis with or without kyphosis, and flattened irregular cervical vertebrae.
None
The disease is caused by variants affecting the gene represented in this entry.
Spondylometaphyseal dysplasia Kozlowski type
SMDK
A form of spondylometaphyseal dysplasia, a group of short stature disorders distinguished by abnormalities in the vertebrae and the metaphyses of the tubular bones. It is characterized by postnatal dwarfism, significant scoliosis and mild metaphyseal abnormalities in the pelvis. The vertebrae exhibit platyspondyly and overfaced pedicles.
None
The disease is caused by variants affecting the gene represented in this entry.
Metatropic dysplasia
MTD
A severe spondyloepimetaphyseal dysplasia characterized by short limbs with limitation and enlargement of joints and usually severe kyphoscoliosis. Radiologic features include severe platyspondyly, severe metaphyseal enlargement and shortening of long bones.
None
The disease is caused by variants affecting the gene represented in this entry.
Neuronopathy, distal hereditary motor, autosomal dominant 8
HMND8
A form of distal hereditary motor neuronopathy, a heterogeneous group of neuromuscular disorders caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.
None

Charcot-Marie-Tooth disease, axonal, 2C
CMT2C
An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy.
None

Digital arthropathy-brachydactyly, familial
FDAB
A disorder characterized by irregularities in the proximal articular surfaces of the distal interphalangeal joints of the hand. Individuals appear normal at birth, with no clinical or radiographic evidence of a developmental skeletal dysplasia. The earliest changes appear during the first decade of life. By adulthood, all interphalangeal, metacarpophalangeal, and metatarsophalangeal joints are affected by a deforming, painful osteoarthritis. The remainder of the skeleton is clinically and radiographically unaffected.
None

Avascular necrosis of the femoral head, primary 2
ANFH2
A disease characterized by mechanical failure of the subchondral bone, and degeneration of the hip joint. It usually leads to destruction of the hip joint in the third to fifth decade of life. The clinical manifestations, such as pain on exertion, a limping gait, and a discrepancy in leg length, cause considerable disability.
