Long-Term Survival Among Children With Trisomy 13 and Trisomy 18 by Cytogenetic Status.

JAMA network open2025 Sep 02

Trisomy 13 (T13) and trisomy 18 (T18) are chromosomal abnormalities with high mortality rates in the first year of life. Understanding differences in long-term survival between children with full vs mosaic or partial trisomy is crucial for prognosis and health care planning. To examine the differences in 10-year survival between children with full T13 and T18 vs those with mosaic or partial trisomy. This retrospective, population-based cohort study assessed liveborn infants with T13 and T18 in the Texas Birth Defects Registry (deliveries from January 1, 1999, to December 31, 2008). Follow-up was through December 31, 2018 (the last date available at the time of analyses) to allow for 10 years of follow-up for all infants. All analyses were conducted from January 1, 2022, to December 31, 2024. Cytogenetic status (full trisomy vs mosaic or partial trisomy). The primary outcome was survival to 10 years of age, assessed using Kaplan-Meier survival estimates. The association between cytogenetic status and mortality by 10 years of age was assessed using Cox proportional hazards regression to generate hazard ratios (HRs). Population attributable fraction was calculated to determine the percentage of survival attributable to mosaic or partial trisomy status. The study cohort included 798 infants (463 female infants [58.0%]; mean [SD] maternal age, 30.9 [8.0] years) with T13 (n = 295) or T18 (n = 503). Among all cases with T13, 25 infants (8.5%; 95% CI, 5.5%-12.3%) survived to 10 years of age. Similarly, among all infants with T18, 43 (8.6%; 95% CI, 6.3%-11.3%) survived to 10 years of age. Kaplan-Meier survival estimates to 10 years of age were statistically significantly higher among children with mosaic or partial trisomy (13 [25.0%] and 14 [43.8%], respectively) compared with full trisomy (12 [4.9%] and 29 [6.6%], respectively) (both P < .001). Infants with full trisomy had statistically significantly increased 10-year mortality hazards compared with those with mosaic or partial trisomy for both T13 (HR, 2.00; 95% CI, 1.42-2.82) and T18 (HR, 3.34; 95% CI, 2.08-5.38). The results of the calculated proportion of 10-year survival due to the presence of nonfull trisomy status (population attributable fraction) was 41.7% for children with T13 and 27.9% for children with T18. The findings of this cohort study of infants with T13 and T18 support differences in long-term survival based on cytogenetic status and emphasize the need to potentially reassess the context of these conditions generally being considered incompatible with life, particularly for those with mosaic trisomies. These findings offer context surrounding treatment decisions, such as withholding interventions, for affected infants in the future.

Co-Occurrence of Urogenital Anomalies and Congenital Heart Disease in a Child With Alpha-Thalassemia Mental Retardation Syndrome Associated With Chromosome 16 Abnormalities due to Partial Monosomy 16p13.3 and Partial Trisomy 16q22.1-q24.3.

Congenital anomalies2025

We report the case of a 3-year-old girl with alpha-thalassemia/mental retardation linked to chromosome 16 (ATR-16) syndrome. The patient presented with hypotonia, developmental delay, and characteristic facial features including hypertelorism and a broad nasal bridge. Blood test results indicated microcytic anemia and normal iron status, suggestive of thalassemia. Genetic analysis revealed that the patient harbored a 465 kb deletion in the 16p13.3 region and a 19.4 Mb duplication in the 16q22.1-q24.3 region. The patient presented with rare complications of ATR-16 syndrome, including anal fistula, vesicoureteral reflux (VUR), and patent ductus arteriosus (PDA). Comparison of this case with previously reported patients with pure partial trisomy 16q suggested that the duplicated distal 16q region may be a critical locus associated with VUR and PDA.

Prenatal diagnosis of partial duplication chromosome 21q11.2-21q21.1: A case report and literature review.

Taiwanese journal of obstetrics &amp; gynecology2025 Sep

We report the prenatal diagnosis for a small supernumerary marker chromosome derived from chromosome 21q11.2-q21.1. A 40-year-old woman presenting at 13 weeks of gestation underwent noninvasive prenatal testing (NIPT) due to advanced maternal age. A positive finding for trisomy 21 urged genetic counseling and subsequent amniocentesis. Amniocentesis revealed a karyotype of 47, XX,+mar. The parental karyotypes were normal, and prenatal ultrasound findings were unremarkable. At a follow-up genetic counseling session, additional prenatal genetic testing was undertaken, specifically, amniocentesis including microarray-based comparative genomic hybridization (aCGH). The aCGH analysis of cultured amniocytes revealed a 1.4 MB duplication of the 21q11.2-q21.1 segment, which is not associated with Down syndrome, and the couple decided to continue her pregnancy. The infant was born without the symptoms of Down syndrome and remains to be so till six months. We thus present a clinically and genetically unique case of discordant NIPT and aCGH results.

Optical Genome Mapping in Myelodysplastic Syndromes: Clinical Value and Limitations Derived From a Cohort of 236 Patients.

Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc2025 Oct

Identification of cytogenetic abnormalities is critical for the classification and risk stratification of myelodysplastic syndromes (MDS). Optical genome mapping (OGM) is an emerging cytogenomic platform that enables high-resolution genome-wide cytogenetic analysis. We analyzed bone marrow specimens of 236 MDS patients, 149 newly diagnosed and 87 with relapsed/refractory disease, using OGM, conventional karyotyping, and next-generation sequencing analysis. OGM and karyotyping showed concordant results in 68% of cases, including 34% with normal findings by both assays. OGM provided additional information in 27% of patients. Common abnormalities detected exclusively by OGM included chromoanagenesis (n = 33), KMT2A partial tandem duplication (n = 7), and MECOM rearrangement (n = 4). These OGM findings led to disease reclassification and/or changes in risk stratification in 14 patients (9.4%) with newly diagnosed MDS. In contrast, OGM failed to detect small clones or subclones in 5% of patients, resulting in risk group changes in 2% of newly diagnosed MDS patients. We conclude that OGM enhances the cytogenetic assessment of MDS in approximately 25% of patients and leads to a change in disease classification and/or risk stratification in approximately 10% of patients. However, low sensitivity for detecting small clones or subclones remains a limitation of OGM.

[Prenatal diagnosis and genetic analysis of two fetuses with Wolf-Hirschhorn syndrome].

Zhonghua yi xue yi chuan xue za zhi = Zhonghua yixue yichuanxue zazhi = Chinese journal of medical genetics2024 Oct 10

To explore the prenatal ultrasound phenotype and genetic basis of two fetuses with Wolf-Hirschhorn syndrome (WHS). A retrospective analysis was conducted on the ultrasound imaging data of two fetuses suspected for WHS at the Prenatal Diagnostic Center of Qingyuan People's Hospital in July 2017 and August 2019, respectively. Amniotic fluid samples of the two fetuses were subjected to chromosomal karyotyping and chromosomal microarray analysis (CMA). This study was approved by the Qingyuan People's Hospital (Ethics No. IRB-2022-064). Prenatal ultrasound examination of the two fetuses had consistently revealed WHS-associated traits including intrauterine growth restriction (IUGR), craniofacial abnormalities and cardiovascular anomalies. Karyotyping analysis suggested that both fetuses had harbored cryptic chromosomal translocations involving partial deletion of 4p. And parental verification revealed that it was de novo for fetus 1 and paternal for fetus 2. CMA has confirmed that fetus 1 had an approximately 8.7 Mb deletion at 4p16.3p16.1 and a 6.8 Mb duplication at 8p23.1p23.1, whilst fetus 2 had a 20.05 Mb deletion at 4p16.3p15.31 and a 7.66 Mb duplication at 9p24.3p24.1. The karyotype of fetus 1 was determined as 46,XN,der(4)t(4;8)(p16.1;p23.1)dn.arr[hg19]4p16.3p16.1(68345_8721580)×1, 8p23.3p23.1(158048_6933745)×3, and that of fetus 2 was determined as 46,XN,der(4)t(4;9)(p15.3;p24)pat.arr[hg19]4p16.3p15.31(68345_20116061)×1, 9p24.3p24.1(208454_7868292)×3. The 4p deletion is probably the main cause for the WHS phenotype in both fetuses. WHS should be suspected when IUGR, renal anomalies, craniofacial and cardiovascular abnormalities are detected upon prenatal ultrasound screening.
