Primary immunodeficiency or monogenic inflammatory bowel disease v4.83 | TFRC |
Achchuthan Shanmugasundram changed review comment from: Comment on list classification: Although there were eight unrelated families reported with immunodeficiency (MIM #616740), they all harboured the same homozygous variant p.Tyr20His. Functional studies and mouse model provide supporting evidence in associating TFRC with green rating in this panel. Although this variant is found in a homozygous region that is identified between two different families from different geographic regions in PMID:26642240, the segregation of this variant with the phenotype supports this gene-disease association. Hence, this gene can be promoted to green rating in the next GMS review.; to: Comment on list classification: Although there were eight unrelated families reported with immunodeficiency (MIM #616740), they all harboured the same homozygous variant p.Tyr20His.

Achchuthan Shanmugasundram changed review comment from: PMID:26642240 - c.58T>C (p.Tyr20His) variant was present in homozygous state in patients A1 and A2 from the family from Kuwait and unaffected father had the same variant in heterozygous state. This variant segregated perfectly with the combined immunodeficiency phenotype in 34 available family members and was absent from multiple variant databases and 731 genotyped controls. The same homozygous variant was found in patient B1 from Western Saudi Arabian family, while this variant was present in heterozygous state in his parents and his sister. Although the families were from different geographic regions and not known to be related, Patient B1 shares a homozygous haplotype with the five genotyped patients from Family A across a 3.3 Mb interval at chromosome 3q29-ter that includes TFRC, suggesting identical by descent inheritance of the mutation from an unknown common ancestor. Functional evidence shows that this substitution disrupts the TfR1 internalization motif, resulting in defective receptor endocytosis and markedly increased TfR1 expression on the cell surface. Iron citrate rescued the lymphocyte defects, and expression of wild-type but not mutant TfR1 rescued impaired transferrin uptake in patient-derived fibroblasts. In addition, transgenic mice homozygous for the human TFRC mutation Y20H were viable and recapitulated the human phenotype. PMID:32851577 - Eight patients from six different tribes of Arab descent were identified with the same previously reported homozygous variant (p.Tyr20His) and they all presented with recurrent sinopulmonary infections, chronic diarrhea, and failure to thrive in early life. This gene has been associated with relevant phenotypes in both OMIM (MIM #616740) and Gene2Phenotype (with 'limited' rating in the DD panel).; to: PMID:26642240 - c.58T>C (p.Tyr20His) variant was present in homozygous state in patients A1 and A2 from the family from Kuwait and unaffected father had the same variant in heterozygous state.
