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

[vel′ō·kär′dē·ō·fā′shəl]
an autosomal-dominant syndrome of cardiac defects and characteristic craniofacial abnormalities, including cleft palate, jaw abnormalities, and prominent nose. It is often associated with abnormalities of chromosome 22. Learning disabilities occur often; short stature, slender hyperextensible hands and digits, scoliosis, mental retardation, inguinal hernia, auricular abnormalities, and microcephaly occur less frequently. Also called Shprintzen's 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.
