alopecia, failure to thrive, small face, recessed jaw
enlarged hands and feet, skull expansion at fontanelle, enlarged tongue
poor muscle tone, slanted eyes, single palmar crease

Number 4 is correct.
Achondroplasia is a type of dwarfism marked by shortened proximal limbs, short fingers and toes, a large head, and a small midface with a flattened nasal bridge. Physical characteristics such as alopecia, failure to thrive, a small face, and a recessed jaw are seen in children with progeria. Enlarged hands and feet, skull expansion at fontanelle, and an enlarged tongue are characteristics found in people with acromegaly. Children with Down syndrome may present with poor muscle tone, slanted eyes, and a single palmar crease.
