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 06, 2023The c.1756T>C (p.Y586H) alteration is located in exon 9 (coding exon 8) of the TGFBRAP1 gene. This alteration results from a T to C substitution at nucleotide position 1756, causing the tyrosine (Y) at amino acid position 586 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
