XLMR syndrome characterized by multiple respiratory infections, hypertelorism, severe CNS deterioration and early death localizes to distal Xq28

H Lubs et al. Am J Med Genet. .

Abstract

We report on a family with severe X-linked mental retardation (XLMR) and progressive, severe central nervous system deterioration. Three of the five affected males died of secondary complications before the age of 10 years and none have survived past the age of 10. These complications included swallowing dysfunction and gastroesophageal reflux with secondary recurrent respiratory infections. In addition, hypotonia and a mild myopathy were also present. All had a characteristic facies, including downslanting palpebral fissures, hypertelorism, and a short nose with a low nasal bridge. The two older boys showed cerebral atrophy by CT. No metabolic abnormalities were identified. Three obligate carriers had an IQ less than 80. The causal gene has been localized distal to DXS8103 in Xq28, a region spanning 5cM. No other XLMR disorder with these manifestations have been localized to this region and this appears to be a new disorder.
