velocardiofacial syndrome


velocardiofacial syndrome

[MIM*192430] a syndrome with hypernasal speech, dysmorphic facial features (long midface, cylindric nose, downward turned corners of mouth), and cardiac abnormalities; same chromosomal abnormality as seen in DiGeorge syndrome (q.v.) (a microdeletion in chromosome 22q11); dominant inheritance. Synonym(s): Shprintzen syndrome

velocardiofacial syndrome

A usually autosomal dominant condition (OMIM:192430) characterised by abnormal pharyngeal arch development that results in defective development of the parathyroid glands, thymus and conotruncal region of the heart.
Molecular pathology
Haploinsufficiency and point mutations of TBX1, a T-box gene that encodes a transcription factor involved in regulating embryonic development, especially of the pharyngeal arch arteries.
