Other genes have however been taken into consideration and investigated in the pathogenesis of ARS; in fact, there seems to be an involvement of a sequence between the PITX2 gene and the noncoding PANCR gene as reported by Qui et al. [13] whose mutation is involved in congenital glaucoma and other forms of glaucoma [38]. This evidence concerns the gene PANCR and Axenfeld-Rieger syndrome.
