Genes affected

ITIH5 (HGNC:21449): (inter-alpha-trypsin inhibitor heavy chain 5) This gene encodes a heavy chain component of one of the inter-alpha-trypsin inhibitor (ITI) family members. ITI proteins are involved in extracellular matrix stabilization and in the prevention of tumor metastasis. They are also structurally related plasma serine protease inhibitors and are composed of a light chain and varying numbers of heavy chains. This family member is thought to function as a tumor suppressor in breast and thyroid cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

Collection Method: clinical testing

The c.2156C>T (p.T719I) alteration is located in exon 13 (coding exon 13) of the ITIH5 gene. This alteration results from a C to T substitution at nucleotide position 2156, causing the threonine (T) at amino acid position 719 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
