High match MOSAIC VARIEGATED ANEUPLOIDY SYNDROME 1; MVA1

Mosaic variegated aneuploidy is an autosomal recessive disorder characterized by mosaic aneuploidies, predominantly trisomies and monosomies, involving multiple different chromosomes and tissues. The proportion of aneuploid cells varies but is usually more than 25% and is substantially greater than in normal individuals. Affected individuals typically present with severe intrauterine growth retardation and microcephaly. Eye anomalies, mild dysmorphism, variable developmental delay, and a broad spectrum of additional congenital abnormalities and medical conditions may also occur. The risk of malignancy is high, with rhabdomyosarcoma, Wilms tumor, and leukemia reported in several cases (summary by Hanks et al., 2004).

Medium match MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH BRAIN AND EYE ANOMALIES), TYPE A, 13; MDDGA13

Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A) is a autosomal recessive disorder associated with severe neurologic defects and resulting in early infantile death. The phenotype includes the alternative clinical designations Walker-Warburg syndrome (WWS) and muscle-eye-brain disease (MEB). The disorder represents the most severe end of a phenotypic spectrum of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as dystroglycanopathies (summary by Buysse et al., 2013).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).

Medium match CYTOMEGALIC CONGENITAL ADRENAL HYPOPLASIA

Congenital adrenal hypoplasia (AHC) is a rare disorder that can be inherited in an X-linked or autosomal recessive (see {240200}) pattern. In X-linked AHC, primary adrenocortical failure occurs because the adrenal glands lack the permanent adult cortical zone. The remaining cells are termed 'cytomegalic' because they are larger than typical fetal adrenal cells (Hay et al., 1981; Reutens et al., 1999).Patients with AHC usually present in early infancy with primary adrenal failure. Hypogonadotropic hypogonadism (HHG) is a hallmark of the disorder, and is recognized during adolescence because of the absence or interruption of normal pubertal development. Abnormal spermatogenesis has also been observed in these patients. Milder forms of the disease have been described, with adrenal insufficiency sometimes occurring in childhood or even early adulthood. A few cases of partial HHG have been reported (summary by Raffin-Sanson et al., 2013). Transient precocious sexual development in infancy or early childhood can be a prominent feature of AHC (Landau et al., 2010).A contiguous gene syndrome involving a combination of congenital adrenal hypoplasia, glycerol kinase deficiency (OMIM ), and Duchenne muscular dystrophy (DMD ) is caused by deletion of multiple genes on chromosome Xp21 (see {300679}).

Medium match GLYCEROL KINASE DEFICIENCY; GKD

Francke et al. (1987) noted that there are 3 clinically distinct forms of glycerol kinase deficiency: infantile, juvenile, and adult. The infantile form is associated with severe developmental delay, and those with the adult form have no symptoms and are often detected fortuitously.The infantile form of GK deficiency, or the 'GK complex,' results from the Xp21 contiguous gene deletion syndrome (OMIM ) with congenital adrenal hypoplasia (OMIM ) and/or Duchenne muscular dystrophy (DMD ), whereas the juvenile and adult forms have isolated GK deficiency (Walker et al., 1996).

Medium match IMAGE SYNDROME

IMAGe syndrome is characterized by the association of Intrauterine growth retardation, Metaphyseal dysplasia (and short limbs), Adrenal hypoplasia congenita, and Genital anomalies. It has been described in less than 20 cases. The patients also present with dysmorphic features (frontal bossing, broad nasal bridge, low-set ears). In boys, genital anomalies include bilateral cryptorchidism, hypospadias, micropenis, and hypogonadotropic hypogonadism. This syndrome is likely to be transmitted as an autosomal recessive trait.

Medium match MYOPATHY, CONGENITAL, WITH FIBER-TYPE DISPROPORTION; CFTD

Congenital fiber-type disproportion (CFTD) myopathy is a genetically heterogeneous disorder in which there is relative hypotrophy of type 1 muscle fibers compared to type 2 fibers on skeletal muscle biopsy. However, these findings are not specific and can be found in many different myopathic and neuropathic conditions. Clarke and North (2003) stated that the diagnosis of 'congenital fiber-type disproportion' as a disease entity is one of exclusion. They also suggested that the nonspecific histologic findings should be termed 'fiber size disproportion,' thus reserving the term CFTD for those cases in which no secondary cause can be found.

Medium match MALIGNANT HYPERTHERMIA, SUSCEPTIBILITY TO, 1; MHS1

Malignant hyperthermia susceptibility (MHS), a skeletal muscle disorder most often inherited as an autosomal dominant trait, is one of the main causes of death due to anesthesia. In susceptible people, a malignant hyperthermia episode is triggered by exposure to commonly used volatile anesthetic agents such as halothane or depolarizing muscle relaxants such as succinyl choline. A fulminant MH crisis is characterized by any combination of hyperthermia, skeletal muscle rigidity, tachycardia or arrhythmia, respiratory and metabolic acidosis, and rhabdomyolysis. Except for this susceptibility to triggering agents, MHS patients are not clinically distinguishable from the general population (summary by Monnier et al., 1997). Genetic Heterogeneity of Susceptibility to Malignant HyperthermiaOther MHS loci include MHS2 (OMIM ) on chromosome 17q; MHS3 (OMIM ) on chromosome 7q; MHS4 (OMIM ) on chromosome 3q; MHS5 (OMIM ), caused by mutation in the CACNA1S gene (OMIM ) on chromosome 1q32; and MHS6 (OMIM ) on chromosome 5p.
