Article Synopsis
  • The 22q11.2 region is prone to genetic changes that can lead to several disorders, such as 22q11.2 microdeletion syndrome and Emanuel Syndrome.
  • This study examines mortality rates, average age at death, and risk factors in 223 confirmed patients with 22q11.2 rearrangements, revealing that 21 (9.4%) of them died, predominantly in early childhood.
  • Key findings show that 71.42% of deaths were due to cardiac causes, with a median age of death of 3 months and 18 days, contributing valuable data on mortality associated with these genetic disorders.

Phelan-McDermid syndrome (PMS, OMIM# 606232) results from either different rearrangements at the distal region of the long arm of chromosome 22 (22q13.3) or pathogenic sequence variants in the gene. codes for a structural protein that plays a central role in the formation of the postsynaptic terminals and the maintenance of synaptic structures.

Objective: Prenatal diagnoses of microdeletion syndromes without ultrasound findings in the first and second trimester are always difficult. The objective of this study is to report the prenatal ultrasound findings in four foetuses diagnosed with 17q21.31 microdeletions (Koolen-de Vries syndrome) using chromosomal microarrays (CMA).

NKG2D ligands (NKG2DL) are expressed on various tumor types and immunosuppressive cells within tumor microenvironments, providing suitable targets for cancer therapy. Various immune cells express NKG2D receptors, including natural killer (NK) cells and CD8 T cells. Interactions between NKG2DL and NKG2D receptors are essential for NK-cell elimination of osteosarcoma tumor-initiating cells.

Chromosomal abnormalities are detected in 40-60% of patients with de novo myelodysplastic syndromes (MDS). This study used the FISH technique in 773 patients with de novo MDS without evidence of monosomy 7 (-7) or 7q deletion (7q-) by conventional G-banding cytogenetics (CC) to analyze their prognostic impact by FISH alone. FISH detected -7/7q- in 5.
