Genetics Home Reference:23 MECP2 duplication syndrome is a condition that occurs almost exclusively in males and is characterized by moderate to severe intellectual disability. Most people with this condition also have weak muscle tone in infancy, feeding difficulties, poor or absent speech, seizures that may not improve with treatment, or muscle stiffness (spasticity). Individuals with MECP2 duplication syndrome have delayed development of motor skills such as sitting and walking. Some affected individuals experience the loss of previously acquired skills (developmental regression). Approximately one third of people with this condition cannot walk without assistance. Many individuals with MECP2 duplication syndrome have recurrent respiratory tract infections. These respiratory infections are a major cause of death in affected individuals, with almost half succumbing by age 25.
MalaCards based summary: Mental Retardation, X-Linked Syndromic, Lubs Type, also known as mecp2 duplication syndrome, is related to mental retardation, x-linked, syndromic 13 and distal xq28 microduplication syndrome, and has symptoms including obsolete flat midface, severe global developmental delay and tented upper lip vermilion. An important gene associated with Mental Retardation, X-Linked Syndromic, Lubs Type is MECP2 (Methyl-CpG Binding Protein 2). Affiliated tissues include eye and prostate.
NIH Rare Diseases:45 Mecp2 duplication syndrome is a genetic condition that occurs almost exclusively in males and is characterized by moderate to severe intellectual disability. other signs and symptoms include infantile hypotonia; delayed motor milestones (i.e. sitting up, crawling); recurrent infections; poor or absent speech; seizures; and/or spasticity. mecp2 duplication syndrome occurs when there is an extra copy (duplication) of the mecp2 gene in each cell. this is generally caused by a duplication of genetic material located on the long (q) arm of the x chromosome. the condition is inherited in an x-linked manner. treatment is based on the signs and symptoms present in each person. last updated: 7/23/2015

UniProtKB/Swiss-Prot:67 Mental retardation, X-linked, syndromic, Lubs type: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRXSL patients manifest mental retardation associated with variable features. They include swallowing dysfunction and gastroesophageal reflux with secondary recurrent respiratory infections, hypotonia, mild myopathy and characteristic facies such as downslanting palpebral fissures, hypertelorism and a short nose with a low nasal bridge.
