| myatonia | Lack of normal muscle tone. (09 Oct 1997) |
|---|---|
| myatonia congenita | Atonic pseudoparalysis of congenital origin (neither familial nor hereditary), observed especially in infants and characterised by absences of muscular tone only in muscles innervated by the spinal nerves. Synonym: congenital atonic pseudoparalysis, myatonia congenita, Oppenheim's disease, Oppenheim's syndrome. An indefinite term for a number of congenital neuromuscular disorders that cause generalised myotonia in young children, and that have a benign course (static or regressive). (05 Mar 2000) |
| myatrophy | Derangement in size and number of muscle fibres occurring with aging, reduction in blood supply, or following immobilization, prolonged weightlessness, malnutrition, and particularly in denervation. (12 Dec 1998) |
| myb | <oncogene> An oncogene, originally identified as the transforming gene in avian myeloblastosis virus, encoding a nuclear protein that binds the DNA sequence YAAC(G/T)G. (24 Mar 1998) |
| myc | <oncogene> This proto-oncogene causes cancers (carcinomas and sarcomas) and is found in the avian myelocytomatosis virus. It has been identified in several avian tumours, and encodes a nuclear protein with a leucine zipper motif. If translocated, it can cause Burkitt's lymphoma, if amplified, it can cause lung, breast, and cervical carcinomas. It is found in both chickens and has an analogue in humans which is located on the long arm of chromosome 8. (24 Mar 1998) |
| myc proteins | <molecular biology> Family of proteins involved in control of translation, have a C terminal basic helix loop helix zipper domain. Myc Max heterodimers specifically bind the sequence CACGTG with higher affinity than homodimers of either. (18 Nov 1997) |
