AI Article Synopsis

  • - 17q12 deletion syndrome is a rare genetic condition caused by a specific deletion on chromosome 17, leading to varied health issues in individuals.
  • - A 35-year-old Japanese man was studied, revealing a 1.46 Mb deletion causing multiple health problems, including maturity-onset diabetes, kidney and liver issues, and facial dysmorphic characteristics.
  • - This case adds to our understanding of the diverse symptoms associated with 17q12 deletion syndrome, highlighting its clinical implications.

Article Abstract

17q12 deletion syndrome is a rare chromosomal anomaly with variable phenotypes, caused by the heterozygous deletion of chromosome 17q12. We herein report a 35-year-old Japanese patient with chromosomal 17q12 deletion syndrome identified by de novo deletion of the 1.46 Mb segment at the 17q12 band by genetic analyses. He exhibited a wide range of phenotypes, such as maturity-onset diabetes of the young (MODY) type 5, structural or functional abnormalities of the kidney, liver, and pancreas; facial dysmorphic features, electrolyte disorders; keratoconus, and acquired perforating dermatosis. This case report provides valuable resources concerning the clinical spectrum of rare 17q12 deletion syndrome.

Article Synopsis
  • - The study examined ultrasound findings and SNP-array results for fetuses with 17q12 deletions and duplications during the second and third trimesters, focusing on prenatal characteristics and outcomes.
  • - Data from 16 fetuses with deletions and 7 with duplications were analyzed, revealing significant abnormalities; deletions often led to renal issues, while duplications were associated with cardiovascular and gastrointestinal problems.
  • - Out of the pregnancies, 9 were terminated, while 14 continued; some cases presented multiple severe structural malformations, highlighting the complexity of conditions associated with these genetic variations.

Objectives: To study the clinical and genotypic spectrum of patients with deletions (MODY 5) at a tertiary care hospital.

Methods: This study included four patients from the Department of Endocrinology at Sher-i-Kashmir Institute of Medical Sciences Srinagar with a strong clinical suspicion of MODY 5. Genetic analysis, including a monogenic gene panel comprising 78 genes associated with MODY and other similar forms of monogenic diabetes, was done.

Article Synopsis
  • This study examines the effects of 17q12 copy number variants (CNVs) in fetuses, focusing on their physical characteristics during pregnancy.
  • The analysis included 48 fetuses with 17q12 microdeletions or microduplications, revealing that 94.6% of fetuses with deletions showed significant kidney issues, while those with duplications often had duodenal obstructions and cardiac abnormalities.
  • Despite the complexity and variability of 17q12 CNVs, the research suggests that the immediate outlook for affected fetuses is generally positive.
