“…At birth, trismus was noted in four cases (1,2,4,9), but gradually disappeared with time. In four patients (cases 2, 4, 5 and 7), bronchospasm episodes have persisted, sometimes triggered by hot or cold temperatures (case 7).…”

“…Twelve cases with prolonged survival have been published, the oldest being 16 years old (4)(5)(6)(7)(8)(10)(11)(12)(13). To our knowledge the existence of LIFR mutations is documented for six of them (6)(7)(8)10).…”

“…To accurately compare the clinical outcome of all the patients, we have focused our study only on patients who have survived beyond three years of age (age range: [3][4][5][6][7][8][9][10][11][12][13][14]. Criteria for inclusion were: (i) Criteria for inclusion were characteristic symptoms of SWS including bowed and short lower limbs, internal cortical thickening, wide metaphyses, dysautonomia symptoms.…”
Stüve-Wiedemann syndrome (SWS, OMIM 601559) is a severe autosomal recessive condition caused by mutations in the leukemia inhibitory receptor (LIFR) gene. The main characteristic features are bowing of the long bones, neonatal respiratory distress, swallowing/sucking difficulties and dysautonomia symptoms including temperature instability often leading to death in the first years of life. We report here four patients with SWS who have survived beyond 36 months of age with no LIFR mutation. These patients have been compared with six unreported SWS survivors carrying null LIFR mutations. We provide evidence of clinical homogeneity of the syndrome in spite of the genetic heterogeneity.

“…2 Patients present in the neonatal period or later with feeding difficulties, recurrent chest infections, spontaneous fractures, unexplained episodes of hyperthermia, and paradoxical sweating/shivering. 3 Absent corneal reflexes, decreased blink reflexes, and corneal opacities are recognized features of this syndrome with poor visual outcome being reported. 4,5 Only 1 earlier report described a case of a long-term survivor who had no corneal reflexes but normal tearing and good vision, but this case also described mosaicism.…”
All of our patients showed improved BCVA with the treatment regimen prescribed. Given these children's debilitating orthopedic problems, visual function is important and has hitherto been reported as being poor.
“…[3][4][5] Other characteristic features include autonomic dysregulation with episodes of hyperthermia, and respiratory and swallowing difficulties. 3,12,13 The syndrome is frequently fatal in infancy, although more recent reports have described longer-term survival in patients, 8,[14][15][16][17] permitting better understanding of the natural history. 6 Stu¨ve-Wiedemann was historically also referred to as Schwartz-Jampel syndrome type 2, although the 2 syndromes were later found to be genetically and phenotypically indistinguishable.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
