Many became wheelchairbound as a result. This unique combination of more than one non-epileptic movement disorder and epilepsy deserves further semiological and genetic study both for the patients with CLS and for the wider implications.[ncbi.nlm.nih.gov]
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]
Prenatal ultrasound has afforded insights into many structural and syndromic fetaldisorders. 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 hearingimpairment. 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]
Other features may include hearingimpairment, awkward gait, and heart and kidney involvement. Onset in postnatal period. It is transmitted with X-linked intermediate inheritance. We thank Pavlo Milan for information submitted. Bibliography G. S.[whonamedit.com]

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]
Typically, male patients are of short stature and exhibit a characteristic coarseface 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]
Furthermore, a coarseface 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]
Although the syndrome has been elucidated clinically, few, if any, studies have focused on the cognitivedeficits of the affected males or carrier females.[ncbi.nlm.nih.gov]
Patients are usually short with delayedboneage; 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]

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 CLS. Benzodiazepine medication is sometimes prescribed. Treatment is symptomatic and supportive, and may include physical and speech therapy and educational services.[secure.ssa.gov]
Management and treatment There is no specific treatment. Prognosis Prognosis is poor and depends on the severity of the disease. The documents contained in this web site are presented for information purposes only.[orpha.net]
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]
The prognosis for individuals with Coffin-Lowry syndrome varies depending on the severity of the symptoms. Early intervention may improve the outlook for patients. Some individuals with Coffin-Lowry syndrome have a reduced life span.[sharecare.com]

However, the etiology of the very first familial case, which was described in 1971 by Lowry with detailed phenotype and coined the term CLS, has remained unknown.[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]

Its etiology is unknown, but it is believed to have an autosomal recessive mode of inheritance. Patients with this syndrome are chromosomally normal. The location of the Coffin-Siris gene has tentatively been identified (3–6) .[journals.lww.com]
