Steroid-resistant nephrotic syndrome type 2 is an autosomal recessive disorder characterized clinically by childhood onset of proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Kidney biopsies show nonspecific histologic changes such as minimal change, focal segmental glomerulosclerosis (FSGS), and diffuse mesangial proliferation. The disorder is resistant to steroid treatment and progresses to end-stage renal failure in the first or second decades (summary by Fuchshuber et al., 1996). Some patients show later onset of the disorder (Tsukaguchi et al., 2002).For a general phenotypic description and a discussion of genetic heterogeneity of nephrotic syndrome and FSGS, see NPHS1 (OMIM ).

Epidermolysis bullosa simplex (EBS) is a clinically and genetically heterogeneous skin disorder characterized by recurrent blistering of the skin following minor physical trauma as a result of cytolysis within basal epidermal cells. Most forms show autosomal dominant inheritance. The Dowling-Meara type of EBS is the most severe form, with generalized blistering that often occurs in clusters (herpetiform), is often associated with hyperkeratosis of the palms and soles, and shows clumping of keratin filaments in basal epidermal cells. The other 2 main types of EBS include the milder generalized Koebner type (OMIM ) and the milder and localized Weber-Cockayne type (OMIM ) (Fine et al., 2008). All 3 forms can be caused by mutation in the KRT5 or the KRT14 gene. See {601001} for a rare autosomal recessive form caused by mutation in the KRT14 gene.

Congenital atransferrinemia is a very rare hematologic disease caused by a transferrin (TF) deficiency and characterized by microcytic, hypochromic anemia (manifesting with pallor, fatigue and growth retardation) and iron overload, and that can be fatal if left untreated.

Erythropoietic protoporphyria-1 is an inborn error of porphyrin metabolism caused by decreased activity of the enzyme ferrochelatase, the terminal enzyme of the heme biosynthetic pathway, which catalyzes the insertion of iron into protoporphyrin to form heme. EPP is characterized clinically by photosensitivity to visible light commencing in childhood, and biochemically by elevated red cell protoporphyrin levels (Todd, 1994). Genetic Heterogeneity of Erythropoietic ProtoporphyriaAlso see X-linked erythropoietic protoporphyria (XLEPP ), caused by mutation in the ALAS2 gene (OMIM ) on chromosome Xp11, and EPP2 (OMIM ), caused by mutation in the CLPX gene (OMIM ) on chromosome 15q22.

Generalized dominant dystrophic epidermolysis bullosa (DDEB-gen) is a subtype of dystrophic epidermolysis bullosa (DEB, see this term), formerly known as DDEB, Pasini and Cockayne-Touraine types, characterized by generalized blistering, milia formation, atrophic scarring, and dystrophic nails.

Epidermolysis bullosa dystrophica is a clinically heterogeneous disorder characterized by blistering and scarring of the skin and mucous membranes in response to mechanical force. Microscopic examination of the skin shows cleavage below the basement membrane within the papillary dermis. All forms are caused by mutation in the COL7A1 gene. Fine et al. (2000) proposed that the Cockayne-Touraine and Pasini subtypes of dystrophic epidermolysis bullosa be combined into 1 category known as 'dominant dystrophic epidermolysis bullosa' (DDEB), since both are caused by mutations in the COL7A1 gene and show overlapping clinical features.Epidermolysis bullosa simplex (see, e.g., {131800}) and epidermolysis bullosa junctional (see, e.g., {226700}) are clinically and genetically distinct disorders characterized by tissue separation at the levels of the basal keratinocyte layer and lamina lucida, respectively.

Ss blood group antigens reside on the red-cell glycoprotein GYPB. The S and s antigens result from a polymorphism at amino acid 29 of GYPB, where S has met29 and s has thr29. The U antigen refers to a short extracellular sequence in GYPB located near the membrane. GYPB, glycophorin A (GYPA ), and glycophorin E (GYPE ) are closely linked on chromosome 4q31. Antigens of the MN blood group (OMIM ) reside on GYPA. The M and N antigens differ at amino acids 1 and 5 of GYPA, where M is ser-ser-thr-thr-gly, and N is leu-ser-thr-thr-glu. The N terminus of GYPB is essentially identical to that of GYPA except that it always expresses the N antigen, denoted 'N' or N-prime. Recombination and gene conversion between GYPA, GYPB, and GYPE lead to hybrid glycophorin molecules and generation of low-incidence antigens. Thus, the MN and Ss blood groups are together referred to as the MNSs blood group system (see {111300}). Recombination results in 3 glycophorin-null phenotypes: En(a-) cells lack GYPA due to recombination between GYPA and GYPB; GYPB-negative (S-s-U-) cells lack GYPB due to recombination in GYPB; and M(k) cells (M-N-S-s-U-) lack both GYPA and GYPB due to recombination between GYPA and GYPE. Individuals with glycophorin-null phenotypes have decreased sialic acid content and increased resistance to malarial infection (see {611162}). GYPA and GYPB are not essential for red-cell development or survival, and GYPA- and GYPB-null phenotypes are not associated with anemia or altered red-cell function (review by Cooling, 2015).
