• A patient with isolated partial trisomy of 11q13.5 → qter
• SNP array results revealed a duplication with a size of 58 Mb.
• Additional findings are separated clavicle, lacrimal duct stenosis renal hypoplasia.
Isolated partial duplication of the long arm of chromosome 11 is very rare. The main features are dysmorphic facial features, pre/postnatal growth retardation, speech delay, mental retardation, hypotonia, microcephaly, and cardiac, vertebral, limb and genital anomalies. In this case, we report a patient with partial trisomy of 11q13.5 → qter due to a de novo rearrangement consisting of the whole X chromosome and part of chromosome 11; 46,X,der(X)(Xqter → Xp22.33::11q13.5 → 11qter). Additional findings were a separated clavicle, lacrimal duct stenosis and prenatally detected renal hypoplasia. SNP array results revealed a duplication between 11q13.5 and 11qter, measuring 58 Mb, from nucleotide 76,601,607 to 134,926,021. As a result, molecular karyotyping could be performed in such cases in order to establish a definite phenotype–genotype correlation using conventional or molecular cytogenetics techniques.
