Presentation
The deletion was not present in the patient's mother's DNA sample, but the father's DNA was unavailable. Currently there are no known treatments. There have been very few reported cases of Primrose syndrome worldwide. [en.wikipedia.org]
A review of literature pertaining to calcification of the external ears is presented. [doi.org]
All the main manifestations were present in our patient. Despite the phenotypic similarity to five other cases, our patient had mild intellectual disability. [ncbi.nlm.nih.gov]

Additional findings are hypotrichosis (sparse hair), cataracts, skin atrophy, dental anomalies and short stature. In most cases intelligence is normal, but some may show mental retardation. [bredagenetics.com]

Obtained from seeds of Oenothera biennis, it is used for its anti-inflammatory effects in the treatment of skin diseases. [medical-dictionary.thefreedictionary.com]
Non-hormonal treatments The placebo effect Part of the reason few PMS treatments provide long-term relief is the so-called 'placebo effect'. [netdoctor.co.uk]
Prognosis
This paper exemplifies our work on developing reliable omics-based predictors for diagnosis and prognosis. [dtls.nl]
Prognosis With proper diagnosis and treatment, most PCOS symptoms can be adequately controlled or eliminated. Infertility can be corrected and pregnancy achieved in most women although, in some, hormonal disturbances and anovulation may recur. [medical-dictionary.thefreedictionary.com]
Etiology
Primrose syndrome (PS) (OMIM#295090) is an extremely rare entity of unknown etiology characterized by the progressive wasting of distal muscles of the legs, the small muscles of the hands resulting in contractures, the presence of intellectual disability [ncbi.nlm.nih.gov]
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]
