A new X linked recessive syndrome of mental retardation and mild dysmorphism maps to Xq28.
Efforts to understand the genetic basis of mental retardation are greatly assisted by the identification of families with multiple relatives with mental retardation that clinical geneticists encounter in the routine practice of their profession. Here we describe a linkage study of a four generation family in which X linked recessive mental retardation (XLMR) is associated with minor dysmorphism...
متن کاملA new X linked syndrome with mental retardation and craniofacial dysmorphism?
We present a syndrome manifested in two half brothers and their two maternal aunts which is characterised in the two boys by severe mental retardation and craniofacial dysmorphism (broad, coarse features and marked plagiocephaly with flattened occiput), and in the aunts merely by moderate mental retardation without dysmorphic features. The brothers do not seem to fall into any previously descri...
متن کاملFine mapping of X-linked clasped thumb and mental retardation (MASA syndrome) in Xq28.
The MASA syndrome is an X-linked disorder with mental retardation, spastic paraparesis, and adducted thumbs as the most characteristic features. We performed linkage analysis, using Xq28 markers, on a large MASA syndrome family. The maximum lodscore was 6.37 at 0 recombination for DXS52 and 5.99 at 0 recombination for DXS305. Crossovers were demonstrated between the disorder and DXS455. Clinica...
متن کاملX-linked mental retardation.
A survey of the mentally retarded children with an IQ between 30 and 55 born in a 10-year period (1955-64) and now of school age was carried out in New South Wales. The number of propositi who had a similarly affected sib of the same sex was ascertained; 58 boys had a similarly affected brother(s) and 22 girls had a similarly affected sister(s). It is suggested that the excess of affected broth...
متن کاملX linked mental retardation: a family with a separate syndrome?
Four males with X linked mental retardation are described. Manifestations similar to those seen in the FG syndrome include severe constipation, tall, broad foreheads, hypotonia, and cowlicks of the hair line, but no individual patient had all the features of the syndrome and none had macrocephaly. The facial appearance was distinctive but different from that seen in the FG syndrome. The cases a...
