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]

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg921*) in the TRPS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TRPS1 are known to be pathogenic (PMID: 11112658). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with clinical features of trichorhinopharyngeal syndrome (PMID: 25792522, 28170084). ClinVar contains an entry for this variant (Variation ID: 438463). For these reasons, this variant has been classified as Pathogenic. -
