Genes affected

ENSG00000286168 (HGNC:):

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: Orphanet, PanelApp Australia, G2P, ClinGen, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.04).
