What progeria is:

Progeria ( AKA Hutchinson-Gilford syndrome) is an extremely rare condition that only affects 64 children today in which, point mutation causes cytosine to replace with thymine inside the cell in a mothers womb, which then
creates an unusable form of Lamin A ( a type of protein) which builds up around the cells nucleus. 

What it causes:

Progeria  causes many problems such as:

• A narrowed face and beaked nose, which makes the child look old           ●  Loose, aged-looking skin
• Delayed and abnormal tooth formation                                                                      ● Loss of body fat and muscle
• Hair loss (alopecia), including eyelashes and eyebrows                                       ● Prominent eyes
• Hardening and tightening of skin on trunk and extremities (scleroderma)         ● Prominent scalp veins
• Head too large for face                                                                                                  ● Slowed growth, with below-average height and weight
• High-pitched voice                                                                                                          ● Small lower jaw (micrognathia)
