Charcot-Marie-Tooth disease intermediate type

A Charcot-Marie-Tooth disease characterized by motor conduction velocities above and below 38 m/s.

primary localized cutaneous amyloidosis 1

A primary cutaneous amyloidosis that has_material_basis_in heterozygous mutation in the gene encoding oncostatin M receptor-beta (OSMR) on chromosome 5p13.

immunodeficiency 23

A combined T cell and B cells immunodeficiency characterized by marked atopy and autoimmunity caused by increased T(H)2 and T(H)17 cytokine production by CD4(+) T cells, T-cell lymphopenia, reduced memory B-cell numbers, recurrent respiratory and skin infections beginning in early childhood, increased serum IgE, and variable developmental delay or intellectual impairment that has_material_basis_in homozygous or compound heterozygous mutation in the PGM3 gene on chromosome 6q14.1.

selective IgM deficiency disease

A selective immunoglobulin deficiency disease thatis a dysgammaglobulinemia resulting from decreased levels of immunoglobulin M (IgM) production to roduction of other antibodies.

androgenic alopecia

An alopecia that is characterized by M-shaped hair line recession and thinning of hair at the crown of the head in males.

indolent plasma cell myeloma

A multiple myeloma that is characterized by M protein in serum and/or urine and evidence of organ damage related the plasma cell neoplasm.

lymphoplasmacytic lymphoma

A B-cell lymphoma characterized by the accumulation of monoclonal cells in the bone marrow and peripheral lymphoid tissues, and associated with the production of serum immunoglobulin M (IgM) monoclonal protein.

histiocytosis-lymphadenopathy plus syndrome

A syndrome characterized by histiocytosis, hyperpigmentation, hypertrichosis, hepatosplenomegaly, heart anomalies, hearing loss, hypogonadism, and reduced height that has_material_basis_in homozygous or compound heterozygous mutation in SLC29A3 on 10q22.1. This syndrome comprises features from 4 histiocytic disorders that were previously considered distinct: Faisalabad histiocytosis, sinus histiocytosis with massive lymphadenopathy, H syndrome, and pigmented hypertrichosis with insulin-dependent diabetes mellitus syndrome.

CD40 ligand deficiency

A combined T cell and B cell immunodeficiency that is a X-linked immunodeficiency with hyperimmunoglobulin M (XHIM) affecting isotype switching and is caused by the absence of CD40 ligand which is normally expressed on activated CD4+ T cells. Individuals with this mutation are unable to switch from IgM to IgG, IgA and IgE.

X-linked mental retardation-hypotonic facies syndrome-1

A syndromic X-linked intellectual disability that is characterized primarily by severe mental retardation, dysmorphic facies, and a highly skewed X-inactivation pattern in carrier women and that has_material_basis_in mutation in the ATRX gene. X-linked mental retardation-hypotonic facies syndrome comprises several syndromes previously reported separately. These include Carpenter-Waziri, Holmes-Gang, and Smith-Fineman-Myers syndromes. X-linked alpha-thalassemia/mental retardation syndrome is an allelic disorder with a similar phenotype with the addition of alpha-thalassemia and Hb H inclusion bodies in erythrocytes.
