Abstract

Casamassima–Morton–Nance syndrome (CMNS) includes a heterogeneous group of spondylocostal dysostosis along with anal atresia and genitourinary abnormalities. In 1981, Casamassima et al first described the syndrome in a fetus, and since then, only seven such cases have been reported so far. CMNS phenotype shows a significant clinical variability as documented in the reported cases. Etiology remains unknown yet, and it carries a poor prognosis. Here, we reported on a young female infant born out of nonconsanguineous marriage with normal karyotype and spondylocostal dysostosis, anal and genitourinary malformations suggesting CMNS. Ours is the eighth, and first case entity of CMNS reported from Asia as per the literature search. In our case, the additional feature of bilateral clubfoot has not been documented earlier in the literature. It extends the clinical spectrum of the syndrome and prompts us to consider it a close differential diagnosis to VACTERL (vertebral defects, anal atresia, cardiac malformations, tracheoesophageal fistula/esophageal atresia, renal anomalies, limb abnormalities) syndrome, which is commonly known and diagnosed. It also raises the question of whether cases of CMNS are being misdiagnosed as VACTERL syndrome due to its rarity.
