Most common symptoms in the clinical presentation of HCM in cats are increased heart rate, heart murmurs and lethargy. (basepaws.com)
In the common Mediterranean variant, mutations decrease production of the Î²-chain (Î²-thalassemia). (valerielebrun.be)

Many mutations map to the polymerase and exonuclease domains of the enzyme and produce a broad clinical spectrum. (biomedcentral.com)

So we had discussions both about the clinical program, about the laboratory science. (nih.gov)
Its unique structure of four divisions (Outpatient Unit, Research Laboratory, Academy, Clinical Research and Study Center) has set the basis for the delivery of best medical practice and state-of-the-art care as well as the establishment/ performance of high quality and patient centered research and translational medicine.

This is the most sensitive test for detecting the mutation in susceptible horses, and requires whole anticoagulated(EDTA) blood. (purdue.edu)

FMF is caused by mutations in the Mediterranean fever (MEFV) gene, which is located on the short (p) arm of chromosome 16 at position 13.3. (scirp.org)

The earliest clinical signs of muscle fasciculations can progress to muscle group spasms, retraction of the lips and eyelids (risussardonicus), stiff jaw, prolapse of the tired eyelid, increased respiratory rate, inspiratorystridor, and stiff gait in more severe cases. (purdue.edu)

Furthermore , POLG analysis optimises clinical management in the early stages of disease and reinforces the need for its evaluation before starting valproic acid treatment. (biomedcentral.com)
Researchers speculate that if family members of affected individuals have a mutation in one copy of the LPL gene in each cell, they may have a mild increase in fat levels in the blood, which could increase their risk of health problems such as heart disease or diabetes. (nih.gov)
The mutations were correlated with clinical presentation and disease severity. (scirp.org)
