- Short Stature
A syndrome with variable characteristics marked mainly by short stature, mental deficiency, microcephaly, postaxial polydactyly, cleft palate, cardiovascular defects, genital malformations, and other abnormalities associated with defective cholesterol [icd10data.com]
Symptoms may include developmental delays, toe defects, slow growth, and short stature. These children generally learn to walk and talk and can acquire other skills, although most do not become independent adults. [myriad.com]
Short stature and restricted growth. Increased size of the ventricles (chambers of the heart). 2) Behavioral or Mental Characteristics: Low intelligence quotient. Hypersensitivity to different stimuli. Aggressiveness and self-injurious behavior. [icliniq.com]

Workup
There are no established guidelines on the diagnostic workup or management of nephrotic syndrome. [aafp.org]
(See Workup .) Treatment for Sjögren syndrome is largely based on symptoms (eg, lotion for dry skin, artificial tears for dry eyes). [emedicine.medscape.com]
Treatment
He hopes to reveal more about the molecular processes that cause SLOS, develop new clinical tests for monitoring disease progression, assess the potential of two possible new treatments, and find out more about how one of the treatments works. [action.org.uk]
C 16 Corticosteroid treatment has no proven benefit, but is recommended by some physicians for persons with nephrotic syndrome who are not responsive to conservative treatment. [aafp.org]

Prognosis
Treatment and prognosis The syndrome carries a poor prognosis with most infants not surviving long after birth. References Promoted articles (advertising) [radiopaedia.org]
Prognosis Prognosis is variable but usually favorable, depending on the severity of malformations and associated ID. * European Reference Network A summary on this disease is available in Deutsch (2004) Español (2020) Français (2020) Nederlands (2020) [orpha.net]
What Is the Prognosis for a Person with Smith-Lemli-Opitz Syndrome? Although serious internal malformations can lead to early death, many people with SLOS can have a normal lifespan with good nutrition and medical care. [myriad.com]
Natural History Complications Prognosis Diagnosis Increased 7-dehydrocholesterol and low cholesterol levels in serum are generally used to diagnose SLOS in addition to presence of family history and clinical symptoms. [wikidoc.org]
Etiology
Etiology The etiology of C syndrome is still unknown. Genetic counseling Although most of the reported patients are sporadic, rare cases of familial occurrence have been described. [orpha.net]
