[[http://www.uniprot.org/uniprot/GNAI3_HUMAN GNAI3_HUMAN]] Defects in GNAI3 are the cause of auriculocondylar syndrome 1 (ARCND1) [MIM:[http://omim.org/entry/602483 602483]]. ARCND1 is an autosomal dominant craniofacial malformation syndrome characterized by variable mandibular anomalies, including mild to severe micrognathia, temporomandibular joint ankylosis, cleft palate, and a characteristic ear malformation that consists of separation of the lobule from the external ear, giving the appearance of a question mark (question-mark ear). Other frequently described features include prominent cheeks, cupped and posteriorly rotated ears, preauricular tags, and microstomia.<ref>PMID:22560091</ref>

[[http://www.uniprot.org/uniprot/GNAI3_HUMAN GNAI3_HUMAN]] Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. G(k) is the stimulatory G protein of receptor-regulated K(+) channels. The active GTP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.<ref>PMID:17635935</ref>  [[http://www.uniprot.org/uniprot/RGS8_HUMAN RGS8_HUMAN]] Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Preferentially binds to G(o)-alpha and G(i)-alpha-3 (By similarity).
