We describe a 23-year-old woman with growth and mental retardation, hypoplasia of the nails and distal phalanges, particularly of the fifth fingers and toes, hirsutism, and a "coarse" face with large mouth and large tongue, and bushy eyebrows. Follow-up from birth to adulthood showed that developmental delay and hypoplasia of nails and distal phalanges are permanent signs. Sparse scalp hair, hypotonia, and feeding difficulties were present in early infancy. Later, growth retardation, hirsutism, and a "coarse" face with midface hypoplasia, broad nose, and large mouth became more impressive. Differential diagnosis includes a number of conditions, particularly Coffin-Siris syndrome, which is the most likely but not completely convincing diagnosis. Therefore, this woman might represent a variant of Coffin-Siris syndrome or a new entity.

Coffin-Siris syndrome is a multiple anomaly/mental retardation syndrome characterized by "coarse" facial appearance, hypoplastic or absent nails on the fifth digits, generalized hirsutism with sparse scalp hair, hypotonia, and developmental delay. Due to several reports of affected sibs with or without a mildly affected parent, both autosomal recessive and autosomal dominant inheritance have been suggested. All previous patients with well-documented Coffin-Siris syndrome are chromosomally normal, and the gene has not been mapped. We report on an infant with typical findings of Coffin-Siris syndrome who also has a de novo apparently balanced translocation of chromosomes 1 and 7, karyotype 46,XY,t(1;7)(q21.3;q34). The parental chromosomes are normal and none of the relatives have signs of Coffin-Siris syndrome. The breakpoints 1q21.3 and 7q34 are suggested as possible locations for a Coffin-Siris gene.

To clarify the phenotypic variability of Coffin-Siris syndrome, we present a review of the literature and 18 new cases. We performed a questionnaire study of patients ascertained through an international support group. Information on their sibs was available for comparison. The most frequent findings include some degree of mental retardation or developmental delay, "coarse" facial appearance, feeding difficulties, frequent infections, and hypoplastic to absent fifth fingernails and fifth distal phalanges. We discuss the key manifestations for diagnosis, medical and developmental implications, and possible pathogenesis.

Coffin-Siris syndrome is a multiple congenital anomaly/mental retardation syndrome with phenotypic variability [OMIM 135900]. The diagnosis is based solely on clinical findings, as there is currently no molecular, biochemical, or cytogenetic analysis available to confirm a diagnosis. Although typically described as an autosomal recessive disorder, autosomal dominant inheritance has also been infrequently reported. We describe a mother and her two daughters who all have features that resemble Coffin-Siris syndrome. However, this is not a completely convincing diagnosis given that hypertelorism is not a feature of Coffin-Siris syndrome and the family is relatively mildly affected. Yet, this family provides further evidence of an autosomal dominant mode of inheritance for a likely variant of Coffin-Siris syndrome (at least in some families). In addition, Sibling 1 had premature thelarche. She is the second reported individual within the spectrum of Coffin-Siris syndrome to have premature thelarche, indicating that it may be a rare clinical feature.

Coffin-Siris syndrome is a rare genetic disease characterized by coarse facial features, sparse scalp hair, hirsutism, hypoplasia of the distal phalanges, hypoplastic nail in the fifth digit, and mental retardation and delayed growth evident in both weight and height. Most cases are sporadic, but the possibility of recessive or dominant autosomal inheritance has been suggested. Facial abnormalities that make intubation difficult and mental retardation that interferes with cooperation are aspects of this disease that can affect the choice of type of anesthesia. We report the case of a parturient with Coffin-Siris syndrome who refused epidural analgesia for labor pain and for whom the obstetrician later decided that an emergency cesarean was necessary due to fetal distress.

We experienced management of general anesthesia in a patients with Coffin-Siris syndrome (CS syndrome) which is an autosomal dominant disorder characterized by mental retardation, growth failure, hypoplasia of the fifth finger's distal phalanx and limb, and syndrome-specific facial appearance. Anesthesia was induced by sevoflurane by mask. After obtaining muscle relaxation by rocuronium, laryngoscopy by Machintosh #2 failed to reveal the vocal cord. However, the vocal cord was revealed by AirwayScope (AWS) for the pediatrics and then tracheal intubation was successful. Surgical procedures and anes-thetic management were performed uneventfully. This case demonstrates usefulness of AWS in pediatric patients with difficult intubation.
