Description : Hereditary folate malabsorption is an autosomal recessive disorder characterized by
signs and symptoms of folate deficiency that appear within a few months after birth.
Infants exhibit low blood and cerebrospinal fluid folate levels with megaloblastic
anemia, diarrhea, immune deficiency, infections, and neurologic deficits. Treatment
with folate supplementation results in resolution of the signs and symptoms. The disorder
is caused by impaired intestinal folate absorption and impaired transport of folate
into the central nervous system (summary by Qiu et al., 2006).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the solute carrier family 46 (folate transporter), member 1
gene (SLC46A1, 611672.0001);
