A Partial Trisomy 2p(p21→pter) Derived from a Paternal t(2;4)(p21;q33) Karyotype
View through CrossRef
A Partial Trisomy 2p(p21→pter) Derived from a Paternal t(2;4)(p21;q33) KaryotypeWe describe a 7-year-old boy with additional material on 4q whose karyotype was 46, XY, der(4) t(2;4)(p21: q33). The father's karyotype was 46, XY, t(2;4)(p21;q33) and the mother's was normal. These results indicate that the extra material on 4q in the patient originated from the father's chromosome 2p. The patient had dysmorphic facial features, prominent ears, long fingers, developmental delay, speech delay and suffered from seizures.

First non‐mosaic case of isopseudodicentric chromosome 18 (psu idic(18)(pter → q22.1::q22.1 → pter) Is associated with multiple congenital anomalies reminiscent of trisomy 18 and 18q− syndrome
AbstractIsopseudodicentric chromosome 18 is very rare and results in a combination of partial trisomy and partial monosomy of chromosome 18. We report here a hypotrophic newborn wi...
