Partial monosomy 7q syndrome due to distal interstitial deletion

A female infant was ascertained at 10 weeks because of failure to thrive and a peculiar cry and was found to have few morphologic variants. Her karyotype was 46,XX,del(7)(q3105::q3405). The parental karyotypes were normal. At one year she manifested physical retardation and development delay and required surgery for gastroesophageal incompetence. The phenotypic characteristics of this patient and those of six previously reported cases of 7q medial or distal interstitial deletion include many anomalies. Morphologic abnormalities of the head, ears, eyes, mouth, chest, hands, feet, and nerves combined with characteristics of birth weight, growth, and development define a detectable syndrome. An unusual cry may help in the recognition of this new syndrome.
