Atlas of Genetics and Cytogenetics in Oncology and Haematology
Dear Colleagues,
The Atlas, once more, is in great danger, and I will have to proceed to a collective economic lay-off of all the team involved in the Atlas before the begining of April 2015 (a foundation having suddenly withdrawn its commitment to support the Atlas). I ask you herein if any Scientific Society (a Society of Cytogenetics, of Clinical Genetics, of Hematology, or a Cancer Society, or any other...), any University and/or Hospital, any Charity, or any database would be interested in taking over the Atlas, in whole or in part. If taking charge of the whole lot is too big, a consortium of various actors could be the solution (I am myself trying to find partners). Could you please spread the information, contact the relevant authorities, and find partners.
Survival of the Atlas will be critically dependant upon your ability to find solutions (and urgently!).
Kind regards.

Donations are also welcome
If each casual visitor gives 3 Euros or Dollars, the Atlas is saved in a week !
If each professional gives 100 Euros or Dollars once a year (now), the Atlas is saved in 2 weeks !
Don't let the Atlas imminent demise
Note: we send fiscal receipts for donations equal or above 50 Euros or Dollars
SDHD (succinate dehydrogenase complex II, subunit D, integral membrane protein)
| Identity |
| Other names | SDH4 (succinate dehydrogenase 4) |
| HGNC (Hugo) | SDHD |
| LocusID (NCBI) | 6392 |
| Location | 11q23.1 |
| Location_base_pair | Starts at 111957548 and ends at 111966525 bp from pter ( according to hg19-Feb_2009) [Mapping] |
| DNA/RNA |
| Description | 8895 bp, 4 exons |
| Transcription | A non transcribed sequence highly homologous to SDHD cDNA is present on chromosome 1p36-p34 |
| Protein |
| Description | 159 amino acids and 17 kDa |
| Expression | widely expressed |
| Localisation | mitochondrial inner membrane |
| Function | Complex II (succinate-ubiquinone oxidoreductase) of the respiratory chain is involved in the oxidation of succinate, carries electrons from FADH to CoQ. It is composed of four nuclear-encoded subunits. The subunit D protein or small subunit (cybS) is one of two integral membrane proteins anchoring the complex to membrane. |
| Homology | The complex II includes SDHC (cybL) and SDHB (iron-sulfur protein) which are also implicated in paragangliomas and pheochromocytomas. |
| Mutations |
| Germinal | Germline mutations cause hereditary paraganglioma. Different types of mutations are described. False-sense mutations, insertions and deletions leading to protein truncation and missense mutations. |
| Somatic | Loss of wild type allele in tumor DNA is usually observed. |
| Implicated in |
| Entity | Hereditary paraganglioma type 1 (also called familial non chromaffin paragangliomas 1, or familial glomus tumor) |
| Disease | Hereditary paraganglioma type 1 (PGL1) is a rare autosomal dominant disorder. The disease is transmitted through fathers and no disease phenotype is transmetted maternally in accordance with a maternal genomic imprinting. Paragangliomas are slow growing highly vascular tumor, usually benign, derived from crest-neural cells. They are preferentially located in the neck (carotid body and glomus vagal) and head (glomus jugulare and tympanicum). They may be associated with pheochromocytomas. |
| Prognosis | It depends on extent of the disease at the time of diagnosis. |
