Abstract: A male patient is reported with terminal 10q26 deletion, developmental retardation, special behaviour, and multiple clinical anomalies including hypotonia, short stature of postnatal onset, short webbed neck, craniofacial dysmorphism, pectus excavatum with widely spaced small nipples, cryptorchidism with scrotal hypoplasia, limb and musculoskeletal anomalies. The facial dysmorphism mainly consisted of trigonocephaly, a long, triangular and asymmetrical face, hypertelorism with pseudoepicanthus, broad nasal bridge, high-arched palate, retrognathia, low-set dysplastic auricles and, on ophthalmologic examination, strabismus, astigmatism and myopia. Some of these clinical stigmata were suggesting the diagnosis of Noonan syndrome. The extremities showed special features including shortening of proximal limbs, brachydactyly with syndactyly of toes II-III and left fingers III-IV, hypoplastic toenails and joint abnormalities. A diastasis of abdominal muscles was noted and, on X-rays a thoracic scoliosis and bilateral coxa valga were evidenced. Analyses of G- and T-banded chromosomes complemented by FISH analyses using different subtelomere probes detected a terminal 10q26 deletion. Subsequent FISH studies using different probes of the 10q26 region were performed in an attempt to closely define the breakpoint and the extent of the deletion and, thereby, to allow karyotype/phenotype comparison between this patient and a previously reported case with an apparently similar 10q26 deletion.
