3 associated diseases with Q15842

[MIM: 272120]: Sudden infant death syndrome (SIDS)

SIDS is the sudden death of an infant younger than 1 year that remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of clinical history. Pathophysiologic mechanisms for SIDS may include respiratory dysfunction, cardiac dysrhythmias, cardiorespiratory instability, and inborn errors of metabolism, but definitive pathogenic mechanisms precipitating an infant sudden death remain elusive. {ECO:0000269|PubMed:21836131}. Note=Disease susceptibility is associated with variants affecting the gene represented in this entry.

[MIM: 239850]: Hypertrichotic osteochondrodysplasia (HTOCD)

A rare disorder characterized by congenital hypertrichosis, neonatal macrosomia, a distinct osteochondrodysplasia, and cardiomegaly. The hypertrichosis leads to thick scalp hair, which extends onto the forehead, and a general increase in body hair. In addition, macrocephaly and coarse facial features, including a broad nasal bridge, epicanthal folds, a wide mouth, and full lips, can be suggestive of a storage disorder. About half of affected individuals are macrosomic and edematous at birth, whereas in childhood they usually have a muscular appearance with little subcutaneous fat. Thickened calvarium, narrow thorax, wide ribs, flattened or ovoid vertebral bodies, coxa valga, osteopenia, enlarged medullary canals, and metaphyseal widening of long bones have been reported. Cardiac manifestations such as patent ductus arteriosus, ventricular hypertrophy, pulmonary hypertension, and pericardial effusions are present in approximately 80% of cases. Motor development is usually delayed due to hypotonia. Most patients have a mild speech delay, and a small percentage have learning difficulties or intellectual disability. {ECO:0000269|PubMed:24176758, ECO:0000269|PubMed:24700710, ECO:0000269|PubMed:28842488}. Note=The disease may be caused by variants affecting distinct genetic loci, including the gene represented in this entry.

7 GO annotations of cellular component

Name Definition
inward rectifying potassium channel A protein complex that comprises four pore-forming (Kir6.x) and four regulatory sulphonylurea receptor (SURx) subunits and forms a transmembrane channel through which ions may pass. The opening and closing of the channel is regulated by ATP: binding of ATP to the Kir6.x subunit inhibits channel activity, whereas binding of Mg2+-complexed ATP or ADP to the SURx subunit stimulates channel activity.
mitochondrion A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
myofibril The contractile element of skeletal and cardiac muscle; a long, highly organized bundle of actin, myosin, and other proteins that contracts by a sliding filament mechanism.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
potassium ion-transporting ATPase complex Protein complex that carries out the reaction: ATP + H2O + K+(out) = ADP + phosphate + K+(in). It is a high affinity potassium uptake system. The E. coli complex consists of 4 proteins: KdpA is the potassium ion translocase, KdpB is the ATPase, and KdpC and KdpF seem to be involved in assembly and stabilization of the complex.
sarcolemma The outer membrane of a muscle cell, consisting of the plasma membrane, a covering basement membrane (about 100 nm thick and sometimes common to more than one fiber), and the associated loose network of collagen fibers.
voltage-gated potassium channel complex A protein complex that forms a transmembrane channel through which potassium ions may cross a cell membrane in response to changes in membrane potential.

6 GO annotations of molecular function

Name Definition
ATP binding Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
ATP-activated inward rectifier potassium channel activity Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel, where the inward rectification is due to a voltage-dependent block of the channel pore by ATP. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force.
ATPase-coupled cation transmembrane transporter activity Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + cation(out) = ADP + phosphate + cation(in).
inward rectifier potassium channel activity Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force. The inward-rectification is due to a voltage-dependent block of the channel pore by a specific ligand or ligands, and as a result the macroscopic conductance depends on the difference between membrane voltage and the K+ equilibrium potential rather than on membrane voltage itself.
sulfonylurea receptor binding Binding to a sulfonylurea receptor, a regulatory subunit of the ATP-sensitive potassium ion channel.
voltage-gated potassium channel activity involved in ventricular cardiac muscle cell action potential repolarization Enables the transmembrane transfer of a potassium ion by a voltage-gated channel through the plasma membrane of a ventricular cardiomyocyte contributing to the repolarization phase of an action potential. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.

12 GO annotations of biological process

Name Definition
defense response to virus Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
heart development The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
inorganic cation transmembrane transport A process in which an inorganic cation is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
kidney development The process whose specific outcome is the progression of the kidney over time, from its formation to the mature structure. The kidney is an organ that filters the blood and/or excretes the end products of body metabolism in the form of urine.
membrane repolarization during ventricular cardiac muscle cell action potential The process in which ions are transported across a membrane such that the ventricular cardiomyocyte membrane potential changes in the direction from the positive membrane potential at the peak of the action potential towards the negative resting potential.
potassium ion import across plasma membrane The directed movement of potassium ions from outside of a cell, across the plasma membrane and into the cytosol.
potassium ion transmembrane transport A process in which a potassium ion is transported from one side of a membrane to the other.
potassium ion transport The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
regulation of ion transmembrane transport Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other.
response to exogenous dsRNA Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an exogenous double-stranded RNA stimulus.
response to lipopolysaccharide Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.
transport across blood-brain barrier The directed movement of substances (e.g. macromolecules, small molecules, ions) through the blood-brain barrier.
