  Other findings can include failure to thrive, feeding difficulties, short stature, ophthalmologic abnormalities, microcephaly and hearing loss. [dnatesting.uchicago.edu]

  Feeding difficulties often lead to failure to thrive in infancy. More than 99% of affected individuals have a contiguous gene deletion of the Williams-Beuren syndrome critical region (WBSCR) that encompasses the elastin gene ( ELN ). [ncbi.nlm.nih.gov]

  Quantitative analysis of GAGs was carried out by measuring optical density at 615 nm of Alcian blue-stained GAG spots on electrophoretograms. [ncbi.nlm.nih.gov]

• Fetal Disorder

  Prenatal ultrasound has afforded insights into many structural and syndromic fetal disorders. In this report, the ultrasound findings were of assistance when counselling a patient who presented with a history of Coffin-Lowry syndrome (CLS). [ncbi.nlm.nih.gov]

  Audiological tests revealed profound hearing impairment. Anomalous labyrinths were shown by CT scan of the temporal bones. It is inferred that deafness is one of the symptoms of this syndrome. [ncbi.nlm.nih.gov]

  A 6 year-old, and a 3 year-old boy both had distinct clinical features of Coffin-Lowry syndrome; severe mental and motor retardation, microcephaly, prominent forehead, hypertelorism, large mouth, large ears, large soft hands, puffy tapered fingers, and [ncbi.nlm.nih.gov]

  Furthermore, a coarse face with prominent brow, hypertelorism and thick nasal tissues, can be present. Cognitive function in female heterozygotes is normal or mildly impaired. Diagnosis Is based on clinical examination. [dx.doi.org]

• Coarse Face

  Typically, male patients are of short stature and exhibit a characteristic coarse face with a prominent forehead, orbital hypertelorism, downslanting palpebral fissures, thick lips, a thick nasal septum with anteverted nares, and irregular or missing [ncbi.nlm.nih.gov]

  Carrier females have mild intellectual impairment and short stature, coarse face, prominent lips, soft fleshy hands with thick tapering fingers. [ggc.org]

  Patients are usually short with delayed bone age; joints are hyperextensible. The cognitive function of affected males is usually severely impaired. Patients are hypotonic and may have “drop attacks”. Sensorineural hearing loss has been described. [genedx.com]

  Diagnostic methods Diagnosis is usually based on the clinical presentation and radiological findings (cranial hyperostosis, abnormal shape and end plates of the vertebral bodies, delayed bone age, metacarpal pseudoepiphyses, and tufting of the distal [orpha.net]

Some cases of Coffin-Lowry syndrome recognized episodic drops and it tended to be intractable for medical treatment. We reported here a patient with the Coffin-Lowry syndrome associated with obstructive sleep apnea syndrome (OSAS). [ncbi.nlm.nih.gov]

Treatment There is no cure and no standard course of treatment for Coffin-Lowry syndrome. Treatment is symptomatic and supportive, and may include physical and speech therapy and educational services. [brainfacts.org]

There is no specific treatment for Coffin-Lowry syndrome. [ideas.org.au]

Prognosis The prognosis for individuals with Coffin-Lowry syndrome varies depending on the severity of symptoms. Early intervention may improve the outlook for patients. Life span is reduced in some individuals with Coffin-Lowry syndrome. [brainfacts.org]

However, there remains a paucity of long-term follow-up information on older patients with which to counsel affected families about prognosis. There is also much to be learned about genotype-phenotype correlations. [ncbi.nlm.nih.gov]

Etiology CLS is caused by mutations in the RPS6KA3 gene (Xp22.2-p22.1), which encodes RSK2, a growth-factor-regulated protein kinase. RPS6KA3 mutations are highly heterogeneous and lead to loss of phosphotransferase activity in the RSK2 kinase. [orpha.net]

The pathophysiology of SIDEs is not well understood. [pediatrics.aappublications.org]

Their pathophysiology is not clear so far. They have been termed cataplexy, hyperekplexia, nonepileptic collapses with atonia, or exaggerated startle responses [Havaligi et al., 2007]. [karger.com]

Early recognition of Coffin-Lowry syndrome is important for genetic counseling and prevention of severe skeletal malformations. [ncbi.nlm.nih.gov]

Children with Coffin-Lowry syndrome must receive extensive dental check-up and preventive dental care. They should also have access to speech and language therapies. [medindia.net]
