The 18q deletion is a rare condition with several described features. A common phenotype includes short stature, microcephaly, facial defects, small feet, intellectual disability and hypotonia.We present a rare case of a fetus with del18q22.1q23 whose diagnosis was obtained by amniocentesis after a routine ultrasound at 20 weeks, where a hemivertebra was detected.Congenital hemivertebra is infrequent and is rarely associated with chromosomal anomalies. Expectant management can be advocated in isolated hemivertebra. This report shows that a hemivertebra can be an isolated prenatal finding in del18 so it is important to screen for, and exclude, chromosomal anomalies.

Ring chromosome 18 (r(18)) is a rare chromosomal abnormality characterized by the circular rearrangement of chromosome 18, which presents significant challenges in genotype-phenotype correlations due to variability in deletions across the 18p and 18q arms. We report the case of a pediatric patient with a de novo ring chromosome 18, diagnosed by karyotype analysis and confirmed by high-resolution SNP arrays. The patient exhibited pathogenic copy number variants (CNVs) in the 18p11.

Article Synopsis
  • The study aimed to examine the genetic traits of a child diagnosed with 18q terminal deletion syndrome by analyzing clinical data and conducting genetic tests.
  • A 4-year-and-6-month-old girl showed symptoms like short stature, intellectual disability, and various physical anomalies, and was found to have a specific chromosomal deletion (del(18)(q21)).
  • The findings suggest that the 18q terminal deletion may be the cause of her multiple congenital issues and intellectual challenges, supported by a review of existing literature on similar cases.

[Comprehensive diagnosis and genetic analysis of two children with ring chromosome 18].

Zhonghua Yi Xue Yi Chuan Xue Za Zhi

September 2024

Institute of Pediatric Medicine, Henan Provincial Key Laboratory of Children's Genetics and Metabolic Diseases, Children's Hospital Affiliated to Zhengzhou University, Henan Children's Hospital, Zhengzhou Children's Hospital, Zhengzhou, Henan 450018, China.

Objective: To clarify the genetic diagnosis of two children with ring chromosome 18 and explore their mechanisms and clinical phenotypes.

Methods: Two patients treated at the Children's Hospital of Henan Province respectively in June 2022 and March 2023 were selected as the study subjects. Genetic testing and diagnosis were carried out through copy number variation sequencing (CNV-seq), G-banded chromosomal karyotyping, and whole exome sequencing (WES).

18q Deletion Syndrome Presenting with Late-Onset Combined Immunodeficiency.

J Clin Immunol

June 2024

Department of Child Health and Development, Graduate School of Medical and Dental Sciences, Tokyo Medical and Dental University (TMDU), 1-5-45 Yushima, Bunkyo-ku, Tokyo, 113-8519, Japan.

Patients with chromosome 18q deletion syndrome generally experience hypogammaglobulinemia. Herein, we describe two patients with chromosome 18q deletion syndrome who presented with late-onset combined immune deficiency (LOCID), which has not been previously reported. Patient 1 was a 29-year-old male with 18q deletion syndrome, who was being managed for severe motor and intellectual disabilities at the Yamabiko Medical Welfare Center for 26 years.

Imaging Findings and MRI Patterns in a Cohort of 18q Chromosomal Abnormalities.

AJNR Am J Neuroradiol

October 2024

From the Department of Diagnostic Imaging (P.M., H.B., M.S., S.B., P.K.), The Hospital for Sick Children, Toronto, Canada.

Background And Purpose: The abnormalities of the long arm of chromosome 18 (18q) constitute a complex spectrum. We aimed to systematically analyze their MR imaging features. We hypothesized that there would be variable but recognizable white matter and structural patterns in this cohort.
