The disease usually is inherited as an autosomal dominant trait; although a few people with hereditary spherocytosis may develop it secondary to new mutations. In addition, there is an autosomal recessive mode of inheritance that also may occur in about 20%-25% of all individuals with hereditary spherocytosis.

Hereditary spherocytosis inheritance

Normal red cells have a doughnut shape where as people with HS have spherical red cells, which have a shortened life span due to destruction by the spleen. Hereditary Spherocytosis, Hereditary Elliptocytosis, and Other Disorders Associated with Abnormalities of the Erythrocyte Membrane Patrick G. Gallagher Bertil Glader This chapter focuses on hemolytic disorders and abnormalities of red blood cell (RBC) shape resulting from alterations of the erythrocyte membrane. In hereditary spherocytosis, there is a lack of spectrin, a key RBC cytoskeletal membrane protein. This produces membrane instability that forces the cell to the smallest volume--a sphere. In the laboratory, this is shown by increased osmotic fragility.

This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell.

It is the most common hereditary hemolytic disorder in people of Hereditary spherocytosis is a familial hemolytic disorder. It is the most common congenital hemolytic disorder due to a defect in the red cell membrane.

A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present.

spherocyto-sis means more sphere-shaped), and this change also makes it more fragile than usual, causing its rupture. (3) HEREDITARY spherocytosis is a heterogeneous disorder characterized by hemolytic anemia, spheroidal red cells, and increased osmotic fragility of erythrocytes. The majority of the patients have an a Hereditary spherocytosis (HS) is the most common congenital hemolytic disorder among individuals of northern European descent. In most cases, it is an autosomal dominant disease that is caused by red blood cell ( RBC ) membrane protein defects, which render the RBCs more vulnerable to osmotic stress and hemolysis . Hereditary spherocytosis type 5, which has been observed predominantly in Japanese individuals, is an autosomal recessive disorder that results in a hemolytic anemia associated with abnormally shaped, osmotically fragile red blood cells (Bouhassira et al., 1992).

Se hela listan på lecturio.com Hereditary spherocytosis (HS) is a familial hemolytic disorder with marked heterogeneity of clinical features, ranging from an asymptomatic condition to a fulminant hemolytic anemia. The disease usually is inherited as an autosomal dominant trait; although a few people with hereditary spherocytosis may develop it secondary to new mutations. In addition, there is an autosomal recessive mode of inheritance that also may occur in about 20%-25% of all individuals with hereditary spherocytosis. With hereditary spherocytosis, a decrease in minimum osmotic resistance is noted when hemolysis of the least persistent red blood cells begins already at a sodium chloride concentration of 0.6-0.7% (norm 0.44-0.48%).

Hereditary spherocytosis and elliptocytosis are the two most common inherited red cell membrane disorders resulting from mutations in genes encoding various red cell membrane and skeletal proteins. HEREDITARY spherocytosis is a heterogeneous disorder characterized by hemolytic anemia, spheroidal red cells, and increased osmotic fragility of erythrocytes. The majority of the patients have an a Hereditary spherocytosis (Minkowski-Schoffar's disease) An autosomal dominant type of inheritance occurs in about 75% of cases. In family members of the patient, the severity of anemia and the degree of spherocytosis can vary. In 25% of cases, there is no family history.

Hereditary spherocytosis can be an autosomal recessive or autosomal dominant trait.

(1992) reported a family in which a dominantly inherited form of hereditary spherocytosis was associated with deficiency of band 3, resulting in an increased spectrin/band 3 ratio. Since deficiency of spectrin is a much more frequent cause of hereditary spherocytosis, the usual finding is a decreased spectrin/band 3 ratio. Neonatal jaundice is commonly encountered in the neonatal period.

Dec 12, 2016 Hereditary spherocytosis (HS) is the most common cause of molytic anemia due to an inherited red blood cell (RBC) membrane disorder.

In addition, there is an autosomal recessive mode of inheritance that also may occur in about 20%-25% of all individuals with hereditary spherocytosis.
