TURNER’S SYNDROME Cause: Woman has only one X
chromosomeHaving only one copy of a chromosome
is called monosomy Symptoms: short in height, failure to
begin puberty, infertility, heart defects, and learning disabilities

KLINEFELTER’S SYNDROME
Cause: Man with more than one X chromosome
Symptoms: Negatively affects testicular growth, which can lead to lower production of testosterone. May also cause reduced muscle mass, reduced body and facial hair, and enlarged breast tissue.

MARFAN’S SYNDROME Cause: Defect in the gene that enables your body
to produce a protein that helps give connective tissue its elasticity and strength
Symptoms: Affects connective tissue most commonly in the heart, eyes, blood vessels and skeleton. Causes individual to be tall and thin with disproportionately long arms, legs, fingers and toes.

ACHONDROPLASIA Cause: defect in the genes affecting
height Symptoms: dwarfism

SICKLE CELL DISEASE Cause: mutation in the gene that tells your body to make hemoglobin, the oxygen carrying compound found in your blood.
Symptoms: red blood cells become rigid, sticky and crescent shaped. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.

PROGERIA Cause: Mutation in the gene that holds
the nucleus of each cell together Symptoms: rapid aging
