Achondroplasia Dwarfism By: Trey A

WHAT IS THE GENETIC CAUSE OF DWARFISM? Is a mutation of the FGFR3 gene located on chromosome 4 IS IT MORE COMMON IN MALE OF FEMALE? Dwarfism affects both male and female but it is found more common in males.

IS IT MORE COMMON IN CERTAIN ETHNIC GROUPS? IT IS MOSTLY FOUND IN CAUCASIAN BUT IS SOMETIMES RARLY FOUND IN AFRICAN AMERICANS HOW OFTEN DOES THIS DISORDER OCCURE? IF ONE PARENT HAS IT IT’S A 50% CHANCE THAT THE KID WILL GET IT. IF BOTH PARENTS HAVE IT IT’S A 50% CHANCE THAT ONE WILL GET IT A 25% CHANCE THAT THE KID WILL BE NORMAL AND 25% CHANCE THE KID WILL JUST BE A LITTLE SHORTER THEN NORMAL BUT NOT DWARFED. 10 in 10000 babies

IS IT DOMINANT OR RECESSIVE? IS IT SEX LINKED OR AUTOSOMAL? It is autosomal. IS IT DOMINANT OR RECESSIVE? It is DOMINANT.

WHAT ARE THE SYMPTOMS OF THIS DISORDER? It makes people abnormally short. Can cause early arthritis It can grind there bones and put them in a wheel-chair because the uneven distribution of there weight CAN IT BE PERDICTED AT BIRTH? It cant be predicted before birth but shortly after the kid is born they will normally develop small bumps.
