Genes affected

TRPS1 (HGNC:12340): (transcriptional repressor GATA binding 1) This gene encodes a transcription factor that represses GATA-regulated genes and binds to a dynein light chain protein. Binding of the encoded protein to the dynein light chain protein affects binding to GATA consensus sequences and suppresses its transcriptional activity. Defects in this gene are a cause of tricho-rhino-phalangeal syndrome (TRPS) types I-III. [provided by RefSeq, Jul 2008]

TRPS1 Gene-Disease associations (from GenCC):

• trichorhinophalangeal syndrome type I

  Inheritance: AD Classification: DEFINITIVE Submitted by: G2P
• trichorhinophalangeal syndrome, type III

  Inheritance: AD Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• trichorhinophalangeal syndrome type I or III

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.608 is higher than 0.05.
