[Tricho-rhino-phalangeal syndrome due to a novel frameshift variation of the TRPS1 gene].

To explore the genetic etiology of a pedigree affected with tricho-rhino-phalangeal syndrome.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.A heterozygous frameshift variation c.1995dupA (p.Gly666Argfs*20) of the TRPS1 gene was detected in the proband but not in her parents.The novel c.1995dupA (p.Gly666Argfs*20) mutation of the TRPS1 gene probably underlies the disease in the proband.
