Reversible severe combined immunodeficiency phenotype secondary to a mutation of the proton-coupled folate transporter.
Hereditary folate malabsorption is a rare inborn error of metabolism due to mutations in the proton-coupled folate transporter (PCFT). Clinical presentation of PCFT deficiency may mimic severe combined immune deficiency (SCID). We report a 4-month-old female who presented with failure to thrive, normocytic anemia, Pneumocystis jirovecii pneumonia and systemic cytomegalovirus infection. Immunolo...
متن کاملThe human proton-coupled folate transporter
This review summarizes the biology of the proton-coupled folate transporter (PCFT). PCFT was identified in 2006 as the primary transporter for intestinal absorption of dietary folates, as mutations in PCFT are causal in hereditary folate malabsorption (HFM) syndrome. Since 2006, there have been major advances in understanding the mechanistic roles of critical amino acids and/or domains in the P...
متن کاملExperimentally optimized threading structures of the proton‐coupled folate transporter
The proton-coupled folate transporter (PCFT, SLC46A1) transports folic acid across the plasma membrane, together with an excess of protons such that the net charge translocation is positive. We developed 3D structural models of PCFT threaded onto the X-ray structures of major facilitator superfamily (MFS) members that were identified as close structural homologues. The model of PCFT threaded on...
متن کاملA case of severe combined immunodeficiency presenting with CMV pneumonia
A five month-old girl was admitted in Ali Asghar Children’s Hospital with a history of three months of fever, cough and dyspnea that her symptoms have exacerbated since two weeks before admission. She was the first child of the family born to consanguineous parents. She was clinically healthy in the past and had gained weight normally and undergone vaccination program with no complication unti...
متن کاملNoncompetitive inhibition of proton-coupled folate transporter by myricetin.
Myricetin is a flavonoid that has recently been suggested to interfere with the intestinal folate transport system. The present study was conducted to examine that possibility, focusing on its inhibitory effect on proton-coupled folate transporter (PCFT) as the molecular entity of the transport system. The uptake transport of folate was first examined in the Caco-2 cell as an intestinal epithel...
