[Tricho-Rhino-phalangeal Syndrome Due to a Novel Frameshift Variation of the TRPS1 Gene].

OBJECTIVE:To explore the genetic etiology of a pedigree affected with tricho-rhino-phalangeal syndrome.METHODS:Next-generation sequencing (NGS) using a gene panel for hereditary osteopathies was carried out for the proband. Suspected mutation was validated in the proband and her parents by Sanger sequencing.RESULTS:A heterozygous frameshift variation c.1995dupA (p.Gly666Argfs*20) of the TRPS1 gene was detected in the proband but not in her parents.CONCLUSION:The novel c.1995dupA (p.Gly666Argfs*20) mutation of the TRPS1 gene probably underlies the disease in the proband.
