Genes affected

TSHZ1 (HGNC:10669): (teashirt zinc finger homeobox 1) This gene encodes a colon cancer antigen that was defined by serological analysis of recombinant cDNA expression libraries. The encoded protein is a member of the teashirt C2H2-type zinc-finger protein family and may be involved in transcriptional regulation of developmental processes. Mutations in this gene may be associated with congenital aural atresia syndrome. [provided by RefSeq, Jan 2012]

Collection Method: clinical testing

The c.65C>T (p.A22V) alteration is located in exon 2 (coding exon 1) of the TSHZ1 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the alanine (A) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
