Study population: The study population consists of individuals diagnosed with cleft lip or cleft lip and palate (CLP). The inclusion criteria are limited to patients with non-syndromic CLP to focus on genetic factors specific to this condition. Patients diagnosed with syndromic CLP, where clefting is associated with other syndromic features or conditions, are excluded to avoid confounding factors and ensure the study's focus remains on non-syndromic cases.

Brief summary: The aim of this work is to study the relation between SNP rs2235371 of IRF 6 gene and Non-Syndromic Cleft Lip and Palate in Egyptian Patients in a prospective study

Detailed description: Infants born with facial deformities, such as cleft lip and palate (CL/P), often face lifelong challenges, including communication issues, aesthetic concerns, and difficulty with swallowing, which impact both health and social behavior. Without treatment, these conditions require specialized care and lead to higher rates of morbidity and mortality. Surgeries, including speech and dental interventions, can help manage these conditions from early childhood . CL/P is one of the most common craniofacial birth defects, affecting populations worldwide, with Asian populations experiencing the highest prevalence at 1/500 live births.

Cleft palate (CP) results from incomplete closure of the palate shelves in early prenatal development. Depending on severity, it may range from a minor fissure to a full gap between the mouth and nasal cavity, necessitating surgical repair. CL/P is categorized as syndromic or non-syndromic, with the latter resulting from failure of palatal fusion between 4-12 weeks of embryogenesis, influenced by factors such as single-gene mutations, chromosomal abnormalities, and environmental interactions.

Key genetic mutations linked to CL/P include those in the IRF6, PVRL1, TP63, FGFR1, and TBX22 genes, with IRF6 SNPs being particularly significant . Family history increases risk, while gene-environment interactions, maternal drug use, non-gestational diabetes, and vitamin deficiencies contribute further. A multidisciplinary approach is essential for managing CL/P, supporting children's functional and aesthetic outcomes from birth through adulthood.
