San Juan Quiahije Chatino Sign Language is an emerging village sign language of the indigenous Chatino villages of San Juan Quiahije and Cieneguilla in Oaxaca, Mexico, used by both the deaf and some of the hearing population. It is apparently unrelated to Mexican Sign Language. As of 2014, there is a National Science Foundation-funded study and also a National Institutes of Health-funded study of the development of this language.
