Summaries for Microcephaly 1, Primary, Autosomal Recessive

About this section
OMIM : 57 Primary microcephaly refers to the clinical finding of a head circumference more than than 3 standard deviations (SD) below the age- and sex-related mean, present at birth. Primary microcephaly is a static developmental anomaly, distinguished from secondary microcephaly, which refers to a progressive neurodegenerative condition. Microcephaly is a disorder of fetal brain growth; individuals with microcephaly have small brains and almost always have mental retardation, although rare individuals with mild microcephaly (-3 SD) and normal intelligence have been reported. Additional clinical features may include short stature or mild seizures. MCPH is associated with a simplification of the cerebral cortical gyral pattern and a slight reduction in the volume of the white matter, consistent with the small size of the brain, but the architecture of the brain in general is normal, with no evidence of a neuronal migration defect (review by Woods et al., 2005). Most cases of primary microcephaly show an autosomal recessive mode of inheritance. Because MCPH directly affects neurogenesis, or neurogenic mitosis, rather than growth of the skull, some prefer the term 'micrencephaly' (Hofman, 1984). MCPH1 in particular is associated with premature chromosome condensation in cell studies (Darvish et al., 2010). (251200)

MalaCards based summary : Microcephaly 1, Primary, Autosomal Recessive, also known as premature chromosome condensation with microcephaly and mental retardation, is related to microcephaly and autosomal recessive primary microcephaly. An important gene associated with Microcephaly 1, Primary, Autosomal Recessive is MCPH1 (Microcephalin 1). Affiliated tissues include brain, cortex and fetal brain, and related phenotypes are microcephaly and intellectual disability

UniProtKB/Swiss-Prot : 75 Microcephaly 1, primary, autosomal recessive: A disease defined as a head circumference more than 3 standard deviations below the age-related mean. Brain weight is markedly reduced and the cerebral cortex is disproportionately small. Despite this marked reduction in size, the gyral pattern is relatively well preserved, with no major abnormality in cortical architecture. Affected individuals are mentally retarded. Primary microcephaly is further defined by the absence of other syndromic features or significant neurological deficits due to degenerative brain disorder. Some MCHP1 patients also present growth retardation, short stature, and misregulated chromosome condensation as indicated by a high number of prophase-like cells detected in routine cytogenetic preparations and poor-quality metaphase G-banding.
