In this report, we present four children (3 males, 1 female) from two families who were aged between 4 11/12 and 10 11/12 years and had clinical findings of 3M syndrome. [mendeley.com]

The purpose of the present work was to analyse the cortical OR through chemosensory event-related potentials (CSERPs) and power spectra calculated by electroencephalogram (EEG) signals recorded in 3M infants: two twins (3M-N) and an additional subject [mdpi.com]

Clinical description Infants present with severe postnatal (and prenatal) growth retardation, usually associated with a low birth weight (<2nd centile). [orpha.net]

• Short Stature

  Physicians should be aware of this entity in the differential diagnosis of children with severe short stature and mild skeletal changes. © Journal of Clinical Research in Pediatric Endocrinology, Published by Galenos Publishing. 3m syndrome Short stature [mendeley.com]

  3-M syndrome is a disorder that causes skeletal abnormalities including short stature (dwarfism) and unusual facial features. [ghr.nlm.nih.gov]

  Description 3-M syndrome is a disorder that causes skeletal abnormalities including short stature (dwarfism) and unusual facial features. [medlineplus.gov]

  Summary Summary 3M syndrome is a growth disorder that causes short stature, characteristic facial features, and skeletal abnormalities. [rarediseases.info.nih.gov]

  Prognosis (please describe): Short stature (−5 to −6 s.d.) [nature.com]

• Male Hypogonadism

  Male hypogonadism and hypospadias. [nature.com]

  Males with three M syndrome have hypogonadism and occasionally hypospadias. Diagnosis/testing. The diagnosis of three M syndrome is established in a proband with characteristic clinical and radiographic features. [ncbi.nlm.nih.gov]

• Developmental Delay

  Although Dubowitz syndrome is also inherited in an autosomal recessive manner, it can be differentiated from 3M by the presence of typical facial features, eczema, microcephaly, and developmental delay. [nature.com]

Treatment The resources below provide information about treatment options for this condition. [rarediseases.info.nih.gov]

In general, the response to treatment is modest, however a trial of treatment over 1 year (GH doses of 35-45 microgram/kg/day with monitoring of serum IGF-I levels) may show a reasonable response. In this case, r-hGH should be continued long-term. [orpha.net]

One of these patients had received growth hormone (GH) treatment which was discontinued due to an inadequate height gain. [mendeley.com]

Treatment is aimed at addressing the growth and skeletal problems and may include surgical bone lengthening, adaptive aids, and physical therapy. [en.wikipedia.org]

Prognosis 3M syndrome is not a life-threatening condition and the prognosis is good. The documents contained in this web site are presented for information purposes only. [orpha.net]

The issues of fertility should be discussed with male patients at the end of puberty and semen analysis offered.[4] 3-M syndrome is not a life-treating condition and the prognosis is good. [en.wikipedia.org]

Prognosis (please describe): Short stature (−5 to −6 s.d.) [nature.com]

Etiology Mutations in the CUL7 gene (6p21.1) are most often responsible for 3M syndrome (67% of cases). Other causal mutations include those in the OBSL1 gene (2q35), in 28% of cases, or the CCDC8 gene (19q13.33), in 5% of cases. [orpha.net]

Summary Epidemiology Approximately 200 cases have been reported to date but as the condition is likely under-recognized, the true figure is probably higher. [orpha.net]

If the test result is positive (please describe): If the test result is negative (please describe): Yes for management of the growth retardation and prevention of recurrence if positive. [nature.com]

Knowing more about the underlying mechanism can reveal new possibilities for treatment and prevention of genetic disorders like 3-M syndrome. [en.wikipedia.org]

Mutations in the CUL7 or OBSL1 gene prevent the cullin-7 protein from bringing together the components of the E3 ubiquitin ligase complex, interfering with the process of tagging unneeded proteins for degradation. [ghr.nlm.nih.gov]

Evaluation of Relatives at Risk It is appropriate to evaluate apparently asymptomatic younger sibs of a proband and at-risk relatives in order to identify as early as possible those who would benefit from prompt initiation of treatment and preventive [ncbi.nlm.nih.gov]
