| syndrome, masa | MASA stands for mental retardation, aphasia, shuffling gait, and adducted thumbs. Features of the syndrome include (1) neurologically: mental retardation and aphasia (lack of speech); (2) limbs: adducted (clasped) thumbs, absent extensor pollicis longus and/or brevis muscles to the thumb, shuffling gait, and leg spasticity; (3) growth: small body size; (4) skeleton: lumbar lordosis (sway back). Masa is inherited as an x-linked trait and so affects mainly boys. Alternative names for masa include clasped thumb and mental retardation, congenital clasped thumb with mental retardation, adducted thumb with mental retardation, and the gareis-mason syndrome.

| syndrome, mucocutaneous lymph node | A syndrome of unknown origin, mainly affecting young children, causing fever, reddening of the eyes more than (conjunctivitis), lips and mucous membranes of the mouth, ulcerative gum disease (gingivitis), swollen glands in the neck (cervical more than lymphadenopathy), and a rash that is raised and bright red (maculoerythematous) in a glove-and-sock fashion over the skin of the hands and feet which becomes hard, swollen (edematous), and peels off. Also called kawasaki's disease. (12 Dec 1998) |

| syndrome, myelodysplastic | A condition in which the bone marrow does not function normally. It does not produce enough blood cells. This condition may progress and become acute leukaemia. Myelodysplastic syndrome also is called preleukaemia or smoldering leukaemia. (12 Dec 1998) |
| syndrome, nail-patella | Hereditary dominant condition with abnormally formed (dysplastic) or absent nails and absent or underdeveloped (hypoplastic) kneecaps (patellae). Other features include iliac horns (symmetrical bilateral central posterior iliac processes), abnormality of the elbows interfering with full range of motion (pronation and supination) and kidney disease resembling glomerulonephritis which.is often mild but can be progressive and lead to renal failure. The nail-patella gene locus found linked genetically to the abo blood group in1965 is now known to be in chromosome region 9q34. Also called onychoosteodysplasia, turner-kieser syndrome, and fong disease. (12 Dec 1998) |

| syndrome, pallister-killian | Condition with multiple malformations at birth and mental retardation due to isochromosome 12p mosaicism (an abnormal chromosome 12 in some cells). (12 Dec 1998) |
| syndrome, patau | Trisomy 13 syndrome or three chromosome number 13s instead of the normal two. Children with this condition have multiple malformations and mental retardation due to an extra chromosome 13 named after the late klaus patau who described the extra chromosome in 1960. This is trisomy 13 syndrome. There are three rather than the normal two chromosomes 13. Children with this syndrome have multiple malformations and mental retardation due to the extra chromosome 13. The malformations commonly include scalp defects, haemangiomas (blood vessel malformations) of the face and nape of the neck, cleft lip and palate, malformations of the heart and abdominal organs, and flexed fingers with extra digits. The mental retardation is profound. The iq is untestably low. The majority of trisomy 13 babies die soon after birth or in infancy. Named after the late klaus patau who discovered the extra chromosome in 1960. (12 Dec 1998) |
| syndrome, pickwickian | The combination of obesity, somnolence, hypoventilation (underbreathing), and plethoric (red) face named after the fat and red-faced boy in a state of somnolency in charles dickens' novel the pickwick papers. (the same boy is thought by some to have had prader-willi syndrome). (12 Dec 1998) |

| syndrome, prader-willi | A condition in children with floppiness (hypotonia), obesity, small hands and feet and mental retardation. It is due to loss of part or all of chromosome 15, specifcally the chromosome 15 from the father. The fat and red-faced boy in a state of somnolency described by charles dickens in his novel the pickwick papers is thought by some to have had prader-willi syndrome. (the same boy inspired the naming of the pickwickian syndrome). (12 Dec 1998) |
| syndrome, proteus | A disturbance of cell growth including benign tumours under the skin, overgrowth of the body, often more on one side than the other (hemihypertrophy), and overgrowth of fingers (macrodactyly). The syndrome is named after the greek god proteus the polymorphous who could change his appearance. The elephant man (john merrick) of 19th century england who was thought to have had neurofibromatosis probably had proteus syndrome. (12 Dec 1998) |
