General Discussion

Chromosome 10, Distal Trisomy 10q is an extremely rare chromosomal disorder in which the end (distal) portion of the long arm (q) of one chromosome 10 (10q) appears three times (trisomy) rather than twice in cells of the body. The disorder is characterized by unusually slow growth before and after birth (prenatal and postnatal growth retardation); abnormally diminished muscle tone (hypotonia); severe mental retardation; and severe delays in the acquisition of skills requiring coordination of mental and muscular activities (psychomotor retardation). Affected infants and children may also have distinctive malformations of the head and facial (craniofacial) area; defects of the hands and/or feet; and/or skeletal, heart (cardiac), kidney (renal), and/or respiratory (pulmonary) abnormalities. The range and severity of symptoms and physical findings may vary from case to case, depending upon the exact length and location of the duplicated portion of chromosome 10q. In most cases, Chromosome 10, Distal Trisomy 10q is due to a chromosomal balanced translocation in one of the parents.

Abstract

Trisomy 10 as the sole cytogenetic abnormality in AML is rare, with an incidence rate of < 0.5%. It tends to affect the elderly and is extremely rare in pediatric patients. We describe a case of an 8-month-old Caucasian baby who presented with prominence of left eye and fever without lymphadenopathy or hepatosplenomegaly. Bone survey showed diffuse periosteal reaction in the femur, pelvis, maxillary and orbital bones (with fracture). CBC revealed normal white blood cell count with increased blasts, mild anemia and moderate thrombocytopenia. Bone marrow biopsy showed increased myeloblasts with bilineage dysplasia and 3-4+ reticulin fibrosis. Flow cytometry revealed blasts positive for CD34, CD33, and MPO and negative for CD7, CD13, and HLA-DR. Trisomy 10 was demonstrated by chromosome analysis and fluorescence in-situ hybridization. The patient received induction chemotherapy and achieved complete clinical and hematologic remission at day 28. However, he relapsed after three cycles of chemotherapy. Compared to the two other reported pediatric cases, our patient has some unique features such as much younger age and additional findings such as bilineage dysplasia and bone marrow fibrosis. Both reported cases and our case were classified as AML-M2 indicating that this may be a common subtype in pediatric patients. Bone involvement was present in our patient and one other case and both had similar immunophenotype (CD33+, CD7-). These findings suggest that isolated trisomy 10 may be associated with distinct clinicopathologic features in pediatric AML. Studies on additional patients are needed to establish this association.

Partial proximal 10q trisomy: a new case associated with biliary atresia.

Hereditas. 2007 Nov

Lysy PA, Sibille C, Gillerot Y, Smets F, Sokal EM.

Gastroenterology and Hepatology Unit, HPED Department, Université Catholique de Louvain & Cliniques Saint Luc, Brussels, Belgium.

Herein we describe a unique case of partial proximal 10q trisomy presenting biliary atresia, anal anteposition and cardiac malformation. The 10q duplication was confirmed by G banding on prophase chromosomes. A review of the literature confirmed that the patient displayed characteristic dysmorphic features of the recently defined partial proximal trisomy 10q syndrome and emphasized the interindividual variability of visceral malformations.

Trisomy 10p and translocation of 10q to 4p associated with selective dysgenesis of IgA-producing cells in lymphoid tissue.

Pathol Int. 2007 Jan

Saiga T, Hashimoto K, Kimura N, Ono H, Hiai H.

Departments of Pathology, Ohtsu Red Cross Hospital, Nagara, Ohtsu, Japan.

A combined chromosomal abberation trisomy of the short arm of chromosome 10 associated with translocation of 10q to chromosome 4p was found in a 14-month-old boy, who died after repeated bouts of pneumonia. The translocation involved the target region 4p16.3 of Wolf-Hirschhorn syndrome and/or Pitt-Rogers-Danks syndrome. The karyotype was 46,XY,der(4)t(4;10)(p16;q11.2),i(10)(p10),ish der(4)t(4;10)(p16.3;q11.2) (D4S96+,D4Z1+),i(10) (pter ++). In addition to growth retardation and external as well as internal dysmorphism, the patient had abnormalities of the immune system, such as thymic involution, generalized lymph node enlargement, unusual distribution of T cells in lymphoid follicles, and selective IgA deficiency. The IgA-producing cells were rarely found in lymph nodes but normally in intestinal mucosa. In contrast, in the lymph nodes, the paracortical T-lymphocytes were hyperplastic, but they rarely entered the primary follicles. It is assumed that the chromosomal abnormality may lead to the dysfunction of T lymphocytes and, further, to the dysgenesis of IgA-producing cells in lymph nodes but not in intestinal mucosa. This suggests that the thymus may differentially control the subsets of IgA-producing cells in lymph nodes and intestinal mucosa.

Trisomy 10p with clinical features of facio-auriculo-vertebral spectrum: a case report.

Clin Dysmorphol. 2006 Jan

Dabir TA, Morrison PJ.

Clinical Genetics department, Belfast City Hospital, Belfast, UK. Tabib.Dabir@bch.n-i.nhs.uk

We report a male child born with complete absence of his external ear, hemifacial microsomia of the right side, high arched palate, a down-turned upper lip and slightly up-slanting palpebral fissures. The features were suggestive of facio-auriculo-vertebral spectrum. Investigations showed a tandem duplication of the short arm of one chromosome 10 with apparent breakpoints at p14 and p15. This case extends the list of chromosomal abnormalities associated with the facio-auriculo-vertebral phenotype and also adds useful clinical information to possible trisomy 10p phenotypes.

Trisomy 10 mosaicism and maternal uniparental disomy 10 in a liveborn infant with severe congenital malformations.

Am J Med Genet A. 2005 Oct

Hahnemann JM, Nir M, Friberg M, Engel U, Bugge M.

Medical Genetics Laboratory Centre, The John F Kennedy Institute, Glostrup, Denmark.

We report on a liveborn infant with trisomy 10 mosaicism combined with maternal uniparental heterodisomy for chromosome 10. The mosaicism 47,XY,+10/46,XY was found in five different tissues, including one blood sample, while cultured lymphocytes from two other blood samples showed a normal karyotype, 46,XY. DNA analysis with six PCR-based microsatellite markers demonstrated the trisomic cell line to be a result of maternal meiotic nondisjunction, and revealed maternal uniparental heterodisomy in the diploid cell line, suggesting that the formation of the diploid cell line was due to trisomy rescue. The boy had severe growth retardation, major dysmorphism, and malformations, and died at 37 days. We reviewed the previous nine reports of infants and fetuses with trisomy 10 mosaicism reported in the literature. We suggest that a common clinical syndrome can be defined comprising skull, jaw and ear abnormalities, cleft lip/palate, malformations of eyes, heart and kidneys, deformity of hands and feet, and most often death neonatally or in early infancy. The cytogenetic findings in the present patient demonstrate the importance of karyotyping more than one tissue, and not only lymphocytes, when a chromosomal aberration is strongly suspected.

Distal trisomy 10q/partial monosomy 14q: an unusual clinical picture.

Genet Couns. 2005

Bregant L, Gersak K, Veble A.

Department Obstetrics and Gynecology, University Medical Centre Ljubljana, Ljubljana, Slovenia. lev.bregant@guest.arnes.si

A case of twin boy with partial trisomy for the distal part of the long arm of chromosome 10 (10q24-->qter) and a concomitant monosomy 14(q32-->qter) is reported. The chromosomal abnormalities resulted from a paternal balanced translocation involving chromosomes 10 and 14. An additional clinical feature was observed, viz. hypoplastic lungs. The proband's phenotype was compared to previously reported patients with partial trisomy 10q or 14q deletion.

Fetal trisomy 10 mosaicism: ultrasound, cytogenetic and morphologic findings in early pregnancy.

Knoblauch H, Sommer D, Zimmer C, Tennstedt C, Heling K, Bollmann R, Bommer C, Tinschert S, Korner H.

Institut fur Medizinische Genetik, Universitatsklinikum Charite, Berlin, Germany.

We report the ultrasound, cytogenetic and morphologic findings in a case of trisomy 10 mosaicism prenatally detected by chorionic villus sampling (CVS). CVS sampling was carried out at the 13th week of gestation because of ultrasound diagnosis of hydrops fetalis and hygroma colli. Trisomy 10 mosaicism was diagnosed in cells from the cytotrophoblast (short-term culture) and the chorionic villus core (long-term culture). Fetal mosaicism was confirmed after termination of pregnancy in umbilical cord cells, placenta and fetal skin fibroblasts.

Partial trisomy 10 mosaicism with cutaneous manifestations: report of a case and review of the literature.

Boon C, Markello T, Jackson-Cook C, Pandya A.

Department of Human Genetics, Medical College of Virginia Richmond, USA.

A female infant with partial trisomy 10 mosaicism and hypomelanosis of Ito is presented. Features include a prominent forehead, hypertelorism, large dysplastic ears, prominent nasal root, a cleft lip and alveolar ridge, bilateral metatarsus adductus, and streaks and whorls of hypopigmented skin. The skin findings were diagnostic for hypomelanosis of Ito. A peripheral blood karyotype was normal. Fibroblasts from a junctional skin biopsy revealed mosaicism for partial trisomy of chromosome 10 [46, XX/47, XX, +del(10) (q11.2q23.2)]. The physical findings of this patient are compared to five published cases of complete trisomy 10 mosaicism and 94 cases of isolated trisomy 10p and trisomy 10q.
