Associated anomalies in asymmetric crying facies and 22q11 deletion.

Congenital asymmetric crying facies, a minor congenital anomaly due to unilateral absence or hypoplasia of the depressor anguli oris muscle, is associated at times with major congenital anomalies. A large number of asymmetric crying facies cases with chromosome 22q11 microdeletions have presently been reported. Fluorescence in situ hybridization (FISH) analysis for 22q11 deletion was performed on 8 infants with asymmetric crying facies. Five of our patients had at least one associated systemic anomaly. Two of 5 patients had conotruncal heart disease (Cayler cardiofacial syndrome). In three of the affected infants, we failed to reveal additional congenital malformation. The 22q11 deletion was present in only one patient. This baby had congenital hypoparathyroidism, severe neonatal hypocalcaemia and tetralogy of Fallot. We suggest, a 22q11 deletion should be excluded not in all cases but in cases with Cayler cardiofacial syndrome and in ACF associated with additional congenital anomalies.
