ADNP syndrome is caused by non-inherited mutations in the ADNP gene. [10] Spanning about 40 kb of DNA, the ADNP gene maps to the chromosomal position chr20q13.13 in the human genome. [9] The protein produced from this gene helps control the activity of other genes through a process called chromatin remodeling.
The patients show failure to thrive, poor appetite, growth retardation, enlarged liver and spleen, prominent osteoporosis and osteopenia, [4] delayed bone age and spontaneous protein aversion. Forced feeding of protein may lead to convulsions and coma. Mental development is normal if prolonged episode of hyperammonemia can be avoided.
D-Bifunctional protein deficiency is an autosomal recessive peroxisomal fatty acid oxidation disorder. Peroxisomal disorders are usually caused by a combination of peroxisomal assembly defects or by deficiencies of specific peroxisomal enzymes .
[10] [11] [12] Mutations in the HADHA or HADHB genes that cause mitochondrial trifunctional protein deficiency disrupt all functions of this enzyme complex. [13] Without enough of this enzyme complex, long-chain fatty acids cannot be metabolized. As a result, these fatty acids are not converted to energy, which can lead to some features of this ...
In medicine, proteinopathy ([pref. protein]; -pathy [suff. disease]; proteinopathies pl.; proteinopathic adj), or proteopathy, protein conformational disorder, or protein misfolding disease, is a class of diseases in which certain proteins become structurally abnormal, and thereby disrupt the function of cells, tissues and organs of the body ...
The GLUT1 protein that transports glucose across the blood brain barrier is encoded by the SLC2A1 gene, located on chromosome 1. [8] In GLUT1 deficiency syndrome, one of the two genes is damaged by a mutation and an insufficient amount protein is made. As a result, insufficient glucose is passing the blood brain barrier.
The normal concentration of plasma protein C is 70 nM (4 μg/mL) with a half live of approximately 8 hours. [2] Healthy term neonates, however, have lower (and more variable) physiological levels of protein C (ranging between 15-55 IU/dL) than older children or adults, and these concentrations progressively increase throughout the first 6 ...
Human Chr 3. In terms of the cause of protein S deficiency it can be in inherited via autosomal dominance.A mutation in the PROS1 gene triggers the condition. The cytogenetic location of the gene in question is chromosome 3, specifically 3q11.1 [6] [7] Protein S deficiency can also be acquired due to vitamin K deficiency, treatment with warfarin, liver disease, kidney disease, chemotherapy ...
