“…Our material, drawn from a prospective survey of consecutive births, gave an incidence of 8 2%. Marino (1953) and Nelson and Eng (1972) stated that the anomaly is not rare. Their data, however, do not provide a basis for an estimation of the incidence of this condition.…”

(1974). Archives of Disease in Childhood, 49, 927. Congenital hypoplasia of depressor anguli oris muscle: a genetically determined condition? The frequency of hypoplasia of the depressor anguli oris muscle was 37 cases among 4 530 consecutive births (8 -2 %). Diagnosis was based on clinical and electromyographic studies. Severe congenital anomalies were detected in 3 of the 37 cases, while another 3 newborns had minor congenital defects. In 17 of the 37 cases there were first-or second-degree relatives with lower lip asymmetry. A minimum of 13 out of the 74 parents of the probands were affected. The high incidence of affection among first-degree relatives of the probands is strong evidence of hereditary factors playing a role in the aetiology of this anomaly.

“…It is often attributed to agenesis of the depressor anguli oris muscle (DAOM) and diminished DAOM electromyographic activity [McHugh et al, 1969;Nelson and Eng, 1972;Papadatos et al, 1974]. However, the DAOM is not absent in all cases [Nelson and Eng, 1972]. Recent evidence suggests that the 22q11 microdeletion, a well-known genetic cause of facial and cardiac anomalies, is more prevalent in ACF infants [Bawle et al, 1998;Innes, 2001].…”

Asymmetric crying face (ACF) is a minor anomaly found in 3-8 per 1,000 births, which may be associated with other anomalies. Previous studies on this topic included small groups of selected subjects, resulting in large variations in findings. The aim of this study was to examine the characteristics and associated anomalies of newborn infants with ACF compared with the general population of newborn infants. The study included newborn infants delivered between 1993 and 2003 at the Department of Neonatology of Rabin Medical Center, Israel. Charts of all newborns diagnosed with ACF were reviewed for obstetric and neonatal details, then compared with non-ACF newborns. ACF was diagnosed in 258 of 67,289 newborns (0.38%), with left-side predominance (77%). Major malformations were found in 7% of ACF infants, 3.5-fold higher than in the total Israeli population. Mild anomalies were present in 15% of the ACF group, and deformations in 4.6%. There was a higher rate of forceps deliveries in the ACF group (RR = 2.73, 95% CI = 1.37-5.42). ACF was more prevalent among females, and the male:female ratio was lower in the ACF group (0.86 vs. 1.06, P = 0.05). The rate of low-birth-weight infants was 3.9% among ACF infants and 9.6% in the control group (RR = 0.41, 95% CI = 0.23-0.76). No significant between-group difference was found for rates of primiparity, macrosomia, prematurity, postmaturity, or size-for-gestational-age. Thus, ACF is associated with a high rate of major malformations. This should prompt clinicians to seek for additional birth defects in ACF infants.
