Summaries for Frontonasal Dysplasia 2

UniProtKB/Swiss-Prot : 66 Frontonasal dysplasia 2: The term frontonasal dysplasia describes an array of abnormalities affecting the eyes, forehead and nose and linked to midfacial dysraphia. The clinical picture is highly variable. Major findings include true ocular hypertelorism; broadening of the nasal root; median facial cleft affecting the nose and/or upper lip and palate; unilateral or bilateral clefting of the alae nasi; lack of formation of the nasal tip; anterior cranium bifidum occultum; a V-shaped or widow's peak frontal hairline.

MalaCards based summary : Frontonasal Dysplasia 2, also known as fnd2, is related to frontonasal dysplasia with alopecia and genital anomaly and frontonasal dysplasia 1, and has symptoms including hypertelorism, depressed nasal bridge and upslanted palpebral fissure. An important gene associated with Frontonasal Dysplasia 2 is ALX4 (ALX Homeobox 4). Affiliated tissues include eye, bone and skin.
