MalaCards based summary: Treacher Collins Syndrome 2, also known as tcs2, is related to polr1d-related treacher collins syndrome and treacher collins syndrome 1, and has symptoms including cleft palate, micrognathia and choanal stenosis. An important gene associated with Treacher Collins Syndrome 2 is POLR1D (RNA Polymerase I Subunit D). Affiliated tissues include bone.

UniProtKB/Swiss-Prot:69 Treacher Collins syndrome 2: A form of Treacher Collins syndrome, a disorder of craniofacial development. Treacher Collins syndrome is characterized by a combination of bilateral downward slanting of the palpebral fissures, colobomas of the lower eyelids with a paucity of eyelashes medial to the defect, hypoplasia of the facial bones, cleft palate, malformation of the external ears, atresia of the external auditory canals, and bilateral conductive hearing loss.
