Full Text

Fraser syndrome (FS) or cryptoptholmos syndrome is a rare inherited disorder characterised by cryptophthalmos, cutaneous syndactyly, malformations of the larynx and genitourinary tract, craniofacial dysmorphism, orofacial clefting, mental retardation and musculoskeletal anomalies. [1] It is named after George Fraser who first described the syndrome in 1962. The incidence of FS is 0.043 per 10,000 live born infants and 1.1 in 10,000 stillbirths with an autosomal recessive inheritance. [2] In an article in 1986, Thomas et al. [3] proposed the diagnostic criteria for FS: Four major (i) cryptophthalmos (ii) syndactyly (iii) genital anomalies and (iv) sibling history of FS; eight minor (i) alterations of nose (ii) ears (iii) larynx (iv) cleft lip and/or palate (v) umbilical hernia (vi) renal agenesis (vii) skeletal anomalies (viii) mental retardation. A diagnosis of FS is suggested if there are at least two major and one minor criteria, or one major and four minor criteria.

Here we are reporting the case of a still born baby with cryptophthalmos delivered by vaginal delivery (pre-term 30-32 weeks) to a primi. She never had ultrasound scans during the antenatal period. The following anomalies were noted: Right cryptophthalmos, syndactyly and micotia thus fitting into FS [Figure 1], [Figure 2], [Figure 3] and [Figure 4].{Figure 1}{Figure 2}{Figure 3}{Figure 4}

Consanguinity is reported in 15-24% of cases. No diagnostic cytogenetic abnormalities have been documented in affected patients. Mutations in genes - Fras1, Frem1 and Frem2 located on long arm of chromosome 4 (4q21) encoding extracellular matrix proteins have been implicated in mouse models. [1] Prenatal diagnosis of FS includes a combination of ultrasound and fetoscopy and is suggested as early as 18 weeks of gestation, particularly in families with affected siblings. FS should be suspected in all cases of stillbirths with renal agenesis. Prevention by genetic counseling would be the best approach, the recurrence rate among siblings being 25%.
