Genes affected

TGFBRAP1 (HGNC:16836): (transforming growth factor beta receptor associated protein 1) This gene encodes a protein that binds to transforming growth factor-beta (TGF-beta) receptors and plays a role in TGF-beta signaling. The encoded protein acts as a chaprone in signaling downstream of TGF-beta. It is involved in signal-dependent association with SMAD4. The protein is also a component of mammalian CORVET, a multisubunit tethering protein complex that is involved in fusion of early endosomes. [provided by RefSeq, Jun 2016]

Sep 30, 2021

The c.1874C>T (p.A625V) alteration is located in exon 10 (coding exon 9) of the TGFBRAP1 gene. This alteration results from a C to T substitution at nucleotide position 1874, causing the alanine (A) at amino acid position 625 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
