Thalassemias are common monogenic diseases DE occurring mostly in Mediterranean and Southeast Asian populations. The DE hallmark of alpha-thalassemia is an imbalance in globin-chain DE production in the adult HbA molecule. The level of alpha chain DE production can range from none to very nearly normal levels. Deletion DE of both copies of each of the two alpha-globin genes causes alpha(0)- DE thalassemia, also known as homozygous alpha thalassemia. Due to the DE complete absence of alpha chains, the predominant fetal hemoglobin is DE a tetramer of gamma-chains (Bart hemoglobin) that has essentially no DE oxygen carrying capacity. This causes oxygen starvation in the fetal DE tissues leading to prenatal lethality or early neonatal death. The DE loss of two alpha genes results in mild alpha-thalassemia, also known DE as heterozygous alpha-thalassemia. Affected individuals have small red DE cells and a mild anemia (microcytosis). If three of the four alpha- DE globin genes are functional, individuals are completely asymptomatic. DE Some rare forms of alpha-thalassemia are due to point mutations (non- DE deletional alpha-thalassemia). DR MIM; 604131; phenotype. DR MedGen; C0002312. DR MeSH; D017085.

The former, an inherited gastrointestinal malignancy DE predisposition, is caused by mutations in SMAD4 or BMPR1A, and the DE latter is a vascular malformation disorder caused by mutations in ENG DE or ACVRL1. All four genes encode proteins involved in the DE transforming-growth-factor-signaling pathway. Although there are DE reports of patients and families with phenotypes of both disorders DE combined, the genetic etiology of this association is unknown. DR MIM; 175050; phenotype.

DE An ocular disease characterized by bilateral, progressive corneal DE opacification, and reduced corneal sensitivity. Onset occurs in the DE first decade, usually between ages 5 and 9. Painful attacks with DE photophobia, foreign body sensations, and recurrent erosions occur in DE most patients. The disease is due to deposition of an unsulfated DE keratan sulfate both within the intracellular space (within the DE keratocytes and endothelial cells) and in the extracellular corneal DE stroma. Macular corneal dystrophy is divided into the clinically DE indistinguishable types I, IA, and II based on analysis of the DE normally sulfated, or antigenic, keratan sulfate levels in serum and DE immunohistochemical evaluation of the cornea. Patients with types I DE and IA macular corneal dystrophy have undetectable serum levels of DE antigenic keratan sulfate, whereas those with type II macular corneal DE dystrophy have normal or low levels, depending on the population DE examined.

DE A disorder occurring in breast-fed infants as a consequence of low DE milk zinc concentration in their nursing mothers, which cannot be DE corrected by maternal zinc supplementation. A large amount of zinc, an DE essential trace mineral, is required for normal growth particularly in DE infants, and breast milk normally contains adequate zinc to meet the DE requirement for infants up to 4 to 6 months of age. Zinc deficiency DE can lead to dermatitis, alopecia, decreased growth, and impaired DE immune function. The disorder shows autosomal dominant inheritance DE with incomplete penetrance. SY Neonatal zinc deficiency due to low breast milk zinc. DR MIM; 608118; phenotype. DR MedGen; C1842485. DR MedGen; C1842486. DR MeSH; D008664. // ID ZTTK syndrome. AC DI-04860 AR ZTTKS.
