AI Article Synopsis

  • The MEIS2 gene is linked to syndromic intellectual disability, specifically featuring cleft palate and cardiac defects.
  • A 10-year-old male patient exhibited cardiac defects, intellectual disability, unique facial features, and gastroesophageal reflux, which led to genetic testing.
  • Whole exome sequencing identified a new mutation in the MEIS2 gene, contributing to the understanding of its role in facial characteristics and various developmental issues.

Article Abstract

Myeloid ecotropic insertion site 2 (MEIS2) gene, encoding a homeodomain-containing transcription factor, has been recently related to syndromic intellectual disability with cleft palate and cardiac defects. Here, we present a male patient, aged 10, with cardiac defects, intellectual disability, facial dysmorphisms and gastroesophageal reflux. Whole exome sequencing revealed a novel de novo nonsense mutation in the MEIS2 gene. This patient represents another reported case with a de novo MEIS2 point mutation and helps to characterize a distinct facial phenotype consisting in low anterior hairline, thin eyebrows, anteverted nares, hypoplastic alae nasi, and M-shape upper lip. Furthermore, these data confirm the role of this gene in cardiac, nervous system development and gastrointestinal function.

Background: Chromosomal inversions are underappreciated causes of rare diseases given their detection, resolution, and clinical interpretation remain challenging. Heterozygous mutations in the MEIS2 gene cause an autosomal dominant syndrome characterized by intellectual disability, cleft palate, congenital heart defect, and facial dysmorphism at variable severity and penetrance.

Case Presentation: Herein, we report a Chinese girl with intellectual disability, developmental delay, and congenital heart defect, in whom G-banded karyotype analysis identified a de novo paracentric inversion 46,XX, inv(15)(q15q26.

This case is the first reported patient with a gene mutation who primarily exhibits pronounced inattention as the main manifestation and is diagnosed with ADHD, requiring methylphenidate treatment. It is characterized by unique clinical features that set it apart from previously reported cases with mutations in the gene. Here, we report a female child with a diagnosis of ADHD and comorbidities.

Article Synopsis
  • The study investigates the differences between smooth muscle cells (SMCs) from two lineages in the proximal thoracic aorta, specifically the second heart field (SHF) and cardiac neural crest.
  • Researchers used advanced techniques like single-cell RNA sequencing and chromatin accessibility assays to analyze these cells in male mice, identifying distinct gene expressions in both lineages.
  • Findings reveal that SHF-derived SMCs have unique transcriptomic profiles that may influence their functions in thoracic aortic diseases, suggesting lineage-specific roles in vascular health.

The Mitf transcription factor is a critical regulator of the melanocyte lineage and eye development. Mitf activity in different cell types is controlled in part by ten alternative promoters and their resulting isoforms. A useful tool for melanocyte-based research, Mitf-cre was designed to express Cre from the Mitf-M promoter, which is melanocyte specific.

Aims: The Cardiac Conduction System (CCS) is progressively specified during development by interactions among a discrete number of Transcriptions Factors that ensure its proper patterning and the emergence of its functional properties. Meis genes encode homeodomain transcription factors (TFs) with multiple roles in mammalian development. In humans, Meis genes associate with congenital cardiac malformations and alterations of cardiac electrical activity, however the basis for these alterations has not been established.
