Genes affected

TFRC (HGNC:11763): (transferrin receptor) This gene encodes a cell surface receptor necessary for cellular iron uptake by the process of receptor-mediated endocytosis. This receptor is required for erythropoiesis and neurologic development. Multiple alternatively spliced variants have been identified. [provided by RefSeq, Sep 2015]

TFRC Gene-Disease associations (from GenCC):

• TFRC-related combined immunodeficiency

  Inheritance: AR, Unknown Classification: DEFINITIVE, MODERATE, SUPPORTIVE, LIMITED Submitted by: G2P, Orphanet, PanelApp Australia, Labcorp Genetics (formerly Invitae), ClinGen

ENSG00000286168 (HGNC:):

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.34).
