Neotenic complex syndrome (NCS) is a syndrome that presents as an extreme form of developmental delay, with the defining characteristic being neoteny of the patient. It was named in 2017 by Dr. Richard F. Walker, who discovered several genes implicated in the syndrome.
Familial adenomatous polyposis is a cancer syndrome in which there are hundreds to thousands of benign adenomas in the colon.. A hereditary cancer syndrome (familial/family cancer syndrome, inherited cancer syndrome, cancer predisposition syndrome, cancer syndrome, etc.) is a genetic disorder in which inherited genetic mutations in one or more genes predispose the affected individuals to the ...
Neoteny is the retention of juvenile traits well into adulthood. In humans, this trend is greatly amplified, especially when compared to non-human primates.
Neoteny and reduction in skull size – grey wolf and chihuahua skulls. When the role of dogs expanded from just being working dogs to also being companions, humans started selective breeding dogs for morphological neoteny, and this selective breeding for "neoteny or paedomorphism" "strengthened the human-canine bond."
Methods used to identify tumors of the peripheral nervous system include a family history of any predisposition syndrome, including neurofibromatosis types 1 and 2, a targeted and comprehensive physical examination, and radiological investigations, the primary one being magnetic resonance imaging.
At Mayo Clinic, FAMMM patients with a confirmed mutation and family history of pancreatic cancer are offered screening with either high-resolution pancreatic protocol CT, MRI, or endoscopic ultrasound starting at age 50 or 10 years younger than the earliest family member with pancreas cancer. They are counseled on the lack of evidence-based ...
Pediatric brain cancer is the second-leading cause of childhood cancer death, just after leukemia. Recent trends suggest that the rate of overall CNS tumor diagnosis is increasing by about 2.7% per year. As diagnostic techniques using genetic markers improve and are used more often, the proportion of AT/RT diagnoses is expected to increase.
For other types of cancer of unknown primary, a PET-CT offers uncertain benefit. [7] The pattern of spread may suggest the location of the primary site. For example, metastatic cancer found in the upper body is more likely to have an origin above the diaphragm, at sites such as the lung and breast. If the metastatic cancer appears first in the ...
