Schwartz-Jampel syndrome (SJS) is a heterogeneous autosomal recessive
syndrome of myotonia and bone dysplasia. Two types have been recognise
d: the classical type with late infantile or childhood manifestation a
nd a rarer form with neonatal manifestation. We report five families w
ith a total of 11 children affected with severe neonatal SJS. All pres
ented after birth with skeletal abnormalities and feeding difficulties
. Five had the typical pursed appearance of the mouth. Nine died from
respiratory complications (five in the neonatal period and four before
2 years of age). One (4 months old) remains hospitalised since birth
requiring continuous oxygen supplementation and one (5 months old) req
uires nasogastric tube feeding and has repeated attacks of aspiration.
Only seven of the 17 previously reported neonatal SJS cases had a sim
ilar course to the patients in this report. We suggest that within neo
natal SJS there is a subgroup which manifests severe respiratory and f
eeding problems and has a poor prognosis. This report brings to the nu
mber of children with neonatal SJS reported from the UAE to 14. This r
epresents the largest review of this syndrome to date from one centre
and indicates that this syndrome is fairly common in the population of
the UAE.
