Children with Liddle’s syndrome are frequently asymptomatic. The first indication of the disease is often the incidental finding of hypertension during a routine physical exam. This syndrome is rare and may only be considered by the treating physician after the child’s hypertension is found to be recalcitrant to antihypertensive agents.

Liddle’s Syndrome is an autosomal dominant disorder that mimics hyperaldosteronism.[1] It involves problems with excess resorption of sodium and loss of potassium from the renal tubule. Hypertension begins at a very early age, often in infancy

Causes include the following:
Losses from translocation
Chromosomal crossovers within a chromosomal inversion
Unequal crossing over
Breaking without rejoining
For synapsis to occur between a chromosome with a large intercalary deficiency and a normal complete homolog, the unpaired region of the normal homolog must loop out of the linear structure into a deletion or compensation loop.
In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is missing. Deletion is the loss of genetic material. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome.[1] Deletions can be caused by errors in chromosomal crossover during meiosis. This causes several serious genetic diseases.
For dentists, this disorder is very important to understand since most of the physical abnormalities are presented in the head, and particularly the oral cavity. Common features are a narrow/high-arched palate, posterior bilateral crossbite, hypodontia (missing some teeth), and increased spacing between teeth. Due to maxillary hypoplasia, Crouzon patients generally have a considerable permanent underbite and subsequently cannot chew using their incisors. For this reason, Crouzon patients sometimes eat in an unusual way–eating fried chicken with a fork, for example, or breaking off pieces of a sandwich rather than taking a bite out of it.
CCFC voluntees plan, organize and participate in many fundraising events throughout the year. Three events are carryed out at a natiional level: the M & M Meat Shops Charity BBQ Day which kicks off the BBQ season each May, the Fall Fundraiser which maintains a local feel occurs sometime in October or November, and the Heel ‘N’ Wheel-a-Thon, a fundrasing walk held in the months of May or June.
The CCFC was started in 1974 by a group of concerned parents who saw the need to raise funds for research into inflammatory bowel disease and to educate patients and their families about these diseases.
In 1992, the Foundation’s name changed to the Crohn’s and Colitis Foundation of Canada from the Canadian Foundation for Ileitis and Colitis in order to more accurately reflect the two most prevalent intestinal disorders. The CCFC has over 65,000 supporters and includes members in some 80 local volunteer groups across Canada.

As public awareness has increased, HD has been depicted increasingly in numerous books, films and TV series. Early works were Arlo Guthrie’s 1969 film Alice’s Restaurant[98] and Jacqueline Susann’s 1966 American novel Valley of the Dolls; more recent references were made in ER,[99] Private Practice,[100] Everwood,[101] All Saints,[102] and House.[103] Steven T. Seagle’s 2004 graphic novel “It’s a Bird” discusses Huntington’s disease and the effects on his family.[104] Many support organizations hold an annual HD awareness event, and some have been endorsed by their respective governments, for example, June 6 is designated “National Huntington’s Disease Awareness Day” by the USA senate, and the UK HDA holds an awareness campaign in the third week of June.[105]
