Abstract
Background-Cartilage-hair hypoplasia (CHH) is an autosomal recessive chondr odysplasia with severe growth failure and impaired immunity. Impaired immun ity may result in increased mortality. Aims-To follow a cohort of 120 CHH patients for mortality from 1971 to 1995 . Methods-The overall and cause specific disease mortality rates in patients with CHH, and the disease mortality rate in 194 parents and 158 non-affecte d sibs were compared with the national rates. Results-During follow up seven disease related deaths were observed versus 0.8 expected (standardised mortality ratio 9.3, 95% confidence interval 3.7 to 19). In most cases, the deaths were confined to the younger age groups and associated with defective immunity. The mortality of the parents and th e non-affected sibs was similar to that in the general population. Conclusion-The study confirms increased mortality in patients with CHH attr ibutable to defective immunity, especially in children.
