achalasia microcephaly syndrome
Achalasia-microcephaly is an extremely rare genetic syndrome, reported in a few families to date, characterized by the association of microcephaly, intellectual deficit and achalasia (with symptoms of coughing, dysphagia, vomiting, failure to thrive and aspiration appearing in infancy/early-childhood). Antenatal exposure to Mefloquine was reported in one simplex case. An autosomal recessive inheritance has been proposed.
