Intellectual functioning disability

Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabiled range. (from Joynt, Clinical Neurology, 1992, Ch55, p28) [from MeSH]

X-linked ichthyosis with steryl-sulfatase deficiency

Ichthyosis is a genetically heterogeneous disorder of the skin. See, e.g., autosomal dominant ichthyosis vulgaris (146700), which is caused by mutations in the filaggrin gene (FLG; 135940). Ichthyosis can also be observed in multiple sulfatase deficiency (272200) (Shapiro, 1977). X-linked ichthyosis is fundamentally the same disorder as placental steroid sulfatase deficiency, which is often first noted in the pregnant mother of affected males by decreased estrogen or delayed progression of parturition (Alperin and Shapiro, 1997). This is thus an example of affinity ('lumping') of phenotypes thought previously to be separate, the opposite of genetic heterogeneity. Schnyder (1970) gave a useful classification of the inherited ichthyoses. Hernandez-Martin et al. (1999) provided a comprehensive review of X-linked ichthyosis. They pointed out that among all genetic disorders X-linked ichthyosis shows one of the highest ratios of chromosomal deletions; complete deletion has been found in up to 90% of patients. [from OMIM]

Griscelli syndrome type 1

Griscelli syndrome type 1 (GS1) represents hypomelanosis with a primary neurologic deficit and without immunologic impairment or manifestations of hemophagocytic syndrome (Menasche et al., 2002). Griscelli syndrome with immune impairment, or Griscelli syndrome type 2 (607624), is caused by mutation in the RAB27A gene (603868). Griscelli syndrome type 3 (609227), characterized by hypomelanosis with no immunologic or neurologic manifestations, can be caused by mutation in the melanophilin (MLPH; 606526) or MYO5A genes. Griscelli syndrome is a rare autosomal recessive disorder that results in pigmentary dilution of the skin and hair, the presence of large clumps of pigment in hair shafts, and an accumulation of melanosomes in melanocytes. While most patients also develop hemophagocytic syndrome, leading to death in the absence of bone marrow transplantation (Menasche et al., 2000), some show severe neurologic impairment early in life without apparent immune abnormalities. Bahadoran et al. (2003) characterized GS1 as comprising hypomelanosis and severe central nervous system dysfunction, corresponding to the 'dilute' phenotype in the mouse, and GS2 as comprising hypomelanosis and lymphohistiocytotic hemophagocytosis, corresponding to the 'ashen' phenotype in mouse. Anikster et al. (2002), Menasche et al. (2002), Huizing et al. (2002), and Bahadoran et al. (2003, 2003) suggested that Elejalde syndrome (256710) in some patients and GS1 represent the same entity. [from OMIM]
