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]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=5.010613E-5).
• BP6: Variant 3-196073940-C-T is Benign according to our data. Variant chr3-196073940-C-T is described in ClinVar as [Benign]. Clinvar id is 1164902.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.547 is higher than 0.05.
