Hereditary folate malabsorption with a novel mutation on SLC46A1: A case report.
Ontology highlight
ABSTRACT: Rationale
Hereditary folate malabsorption (HFM) is characterized by folate deficiency with impaired intestinal folate absorption and impaired folate transport into the central nervous system. Its manifestations mainly include macrocytic anemia, recurrent infections, and neurological deficits. The neurological manifestations include progressive psychomotor retardation, behavioral disorders, and early-onset seizures.Patient concerns
From early infancy, a Chinese boy had experienced macrocytic anemia, leukopenia, thrombocytopenia, recurrent pneumonia, diarrhea, and mouth ulcers. He also presented with progressive neurological symptoms.Diagnosis
A novel mutation in the SLC46A1 gene was identified, and HFM was diagnosed at 18 months of age.Interventions
After the HFM diagnosis, the boy was treated with folinic acid.Lessons
Folinic acid supplementation is effective and may offer life-changing therapy for patients with HFM.
