Long-Term Survival Among Children With Trisomy 13 and Trisomy 18 by Cytogenetic Status.
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.
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.
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.
Fork Stalling and Template Switching in a Complex der(6)dn with Duplication of 6q24.3qter and 6p25.3: A Case Report.
Partial trisomy of the 6q24qter region is a rare chromosomal disorder characterized by variable clinical features and poorly understood mechanistic origins. We describe a de novo complex der(6) chromosome in a patient with features consistent with partial 6q trisomy syndrome, including congenital heart disease, growth restriction, developmental delay, and dysmorphic traits. Molecular Findings: Whole-genome sequencing (WGS) identified duplications of 1.5 Mb on 6p25.3 and 23.3 Mb on 6q24.3-qter. While the 6p duplication appears benign, the phenotype is likely driven by dosage-sensitive 6q genes (ARID1B, TAB2, QKI) and possible additive effects from other duplicated genes. No parental pericentric inversion was detected by classical or molecular cytogenetics, and WGS revealed no inversion-associated breakpoints. Instead, chimeric (q-/q+) and truncated reads at the 6q junction support a replication-based origin, such as reversed template switching. FISH confirmed direct insertion of the 6q segment into 6p25.3, without a del/dup pattern typical of inversion-derived recombinants. Notably, WGS detected no direct 6p-6q junction reads but identified chimeric 6p-15q-6q reads with 2-bp microhomologies, suggesting that chromosome 15 transiently mediated the rearrangement. Interspersed telomeric sequences and flanking Alu elements were also found at both breakpoints. Altogether, these findings support a model in which replication fork stalling and template switching - potentially facilitated by telomere dynamics and repetitive elements - led to the formation of a recombinant-like der(6) chromosome. This case highlights the mechanistic complexity of structural rearrangements and the role of replication-based errors in shaping human genomic variation.
Prenatally Detected Maternally Inherited Partial Duplication of 11p15.5 ICR1 Results in Phenotypes Overlapping Russell-Silver Syndrome in Infancy.
Differentially methylated regions (DMRs) in certain areas of the genome are subject to genomic imprinting. DMRs at chromosome 11p15.5 are associated with Beckwith-Wiedemann syndrome (BWS) and Russell-Silver Syndrome (RSS), two growth disorders with opposite phenotypes. We identified a maternally inherited duplication containing part of the 11p15 DMR in a non-anomalous fetus in first trimester using genome sequencing (GS). The ∼281kb duplication at 11p15.5 contains the entire imprinting control region 1 (ICR1) and the H19 gene but lacks the IGF2 gene and the imprinting control region 2 (ICR2). Methylation studies revealed hypomethylation of ICR1 in fetal cells as well as in the mother (leukocytes), who had a history of feeding difficulties in infancy and short stature. The duplication was inherited from the asymptomatic maternal grandmother of the fetus, who showed hypermethylation of ICR1 in leukocytes suggesting paternal inheritance. The fetus developed decelerating growth in late gestation and phenotypes overlapping those of RSS were noted in infancy. This study adds to the limited literature on partial duplications of the 11p15.5 region and their associated phenotypes, underscoring the efficacy of GS in cases involving DMRs associated with imprinting disorders.
