Protein-coding gene
Pituitary homeobox 3 is aprotein that in humans is encoded by thePITX3 gene .[ 4] [ 5]
This gene encodes a member of the RIEG/PITX homeobox family, which is in the bicoid class ofhomeodomain proteins. Members of this family act astranscription factors . This protein is involved in lens formation during eye development,[ 5] [ 6]
Clinical significance [ edit ] Mutations of this gene have been associated withanterior segment mesenchymal dysgenesis (ASMD) andcongenital cataracts .[ 5]
