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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.1751A>G (p.K584R) alteration is located in exon 9 (coding exon 8) of the TGFBRAP1 gene. This alteration results from a A to G substitution at nucleotide position 1751, causing the lysine (K) at amino acid position 584 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
