Interstitial deletion of the long arm of chromosome 1, del(1)(q21-q25) in a profoundly retarded 8-year-old girl with multiple anomalies


Schinzel, Albert; Schmid, Werner (1980). Interstitial deletion of the long arm of chromosome 1, del(1)(q21-q25) in a profoundly retarded 8-year-old girl with multiple anomalies. Clinical Genetics, 18(4):305-313.

Abstract

An 8-year-old girl revealed the karyotype 46, XX,del(l)(q21 → q25). Both parents had normal chromosomes. The patient showed the following findings: underweight at birth, severe growth deficiency (at 7 9/12 years, length, weight and head circumference were at the levels of 24, 18 and 6 months, respectively), delayed bone age; bilateral cleft lip and cleft palate; a pattern of facial dysmorphic stigmata including a short, bulbous nose, exotropia, anisocoria, absence of some teeth, poorly modeled auricles; very small hands and feet with short fingers and toes, and broad thumbs and big toes exhibiting dysplastic, hyperconvex nails; in radiographs multiple phalangeal cone-shaped epiphyses, bifid terminal phalanges of the thumbs and half-moon shaped terminal phalanges of the big toes and absence of the 12th ribs. The patient suffered from seizures and from recurrent otitis and pyuria. Motor and mental development were profoundly delayed: at 8 years she was unable to sit up, had no speech and barely responded to her environment. As the proband and her parents were Fy$^{a}$/Fy$^{b}$, location of the Duffy locus on segment 1q22 → 1q24 can be excluded.
