Role of ZFHX4 in orofacial clefting based on human genetic data and zebrafish models.

Orofacial clefting (OFC) is a frequent congenital anomaly and can occur either in the context of underlying syndromes or in isolation (nonsyndromic). The two common OFC phenotypes are cleft lip with/without cleft palate (CL/P) and cleft palate only (CPO). In this study, we searched for penetrant CL/P genes, by evaluating de novo copy number variants (CNV) from an exome sequencing dataset of 50 nonsyndromic patient-parent trios.

Anorectal Malformation Patients in Australia and Europe: Different Location, Same Problem? A Retrospective Comparative Registry-Based Study.

Anorectal malformations (ARM) encompass a spectrum of rare congenital defects of the rectum and anus, requiring specialized reconstructive surgery. To improve epidemiological and clinical research in rare diseases such as ARM, collaborative efforts and patient registries are key. This retrospective study pools clinical data over a 30-year period from two ARM patient registries (The Royal Children's Hospital (RCH) in Melbourne, Australia, and the ARM-Network Consortium in Europe).

Identification of a DNA methylation episignature for recurrent constellations of embryonic malformations.

The term "recurrent constellations of embryonic malformations" (RCEM) is used to describe a number of multiple malformation associations that affect three or more body structures. The causes of these disorders are currently unknown, and no diagnostic marker has been identified. Consequently, providing a definitive diagnosis in suspected individuals is challenging.
