TBR1 [SEP] chromosome
on the q arm of the positive strand of chromosome 2. It is 8,954 base pairs in length. "TBR1" is one of the three genes that make up the TBR1 subfamily of T-box genes. The two other genes that form the TBR1 subfamily are "EOMES" (also known as "TBR2") and "TBX21" (also known as "T-BET"). "TBR1" is also known as "T-box Brain Protein", "T-Brain 1", and
which describes the likelihood that two genes are near each other on a chromosome, and thus will be inherited together, areas of strong or suggestive linkage with inheritance of synesthesia were found. The area with the highest LOD score in the genome of an individual with auditory-visual synesthesia has been shown to be linked with autism as well, another disorder with sensory and perceptual abnormalities. Other regions of linkage include genes that are related to the development of the cerebral cortex (TBR1), dyslexia, and apoptosis (EFHC1),
