Genes affected

YWHAH (HGNC:12853): (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein eta) This gene product belongs to the 14-3-3 family of proteins which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals, and this protein is 99% identical to the mouse, rat and bovine orthologs. This gene contains a 7 bp repeat sequence in its 5' UTR, and changes in the number of this repeat have been associated with early-onset schizophrenia and psychotic bipolar disorder.

The c.209C>T (p.T70I) alteration is located in exon 2 (coding exon 2) of the YWHAH gene. This alteration results from a C to T substitution at nucleotide position 209, causing the threonine (T) at amino acid position 70 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
