Variability of 2q37 deletion syndrome features as exemplified by several clinical case reports

2q37 deletion syndrome is characterized by terminal deletions of the long arm of chromosome 2 and a variable clinical picture that includes type E brachydactyly, obesity, delayed motor and psychomotor development, congenital malformations of internal organs and the facial phenotype particular qualities. Authors present the two clinical case reports of patients with 2q37 deletions demonstrating different clinical manifestations. Proband 1 complained exclusively of brachydactyly while proband 2 had almost the full spectrum of clinical symptoms characterizing the syndrome. The Face2Gene AI-Powered Diagnosis & Care Management Tool suggested the correct diagnosis in both cases based on the features of the facial phenotype that in its turn became the key factors in choosing the tactics for further molecular genetic diagnostics. Conclusion: careful collection of anamnesis data, description of the facial phenotype and the use of artificial intelligence-based tools can become the key factors in choosing the tactics for the molecular genetic diagnostics available for practitioners of various specialties.
