Congenital hiatal hernia is a rare congenital defect and often occurs at a sporadic basis, but familial cases have also been reported. Here, we report on a 3-year-old male patient of Middle-Eastern descent, diagnosed at 5 months of age patient presenting with a congenital hiatal hernia, vermis hypoplasia manifested by axial hypotonia and horizontal nystagmus, preauricular tag, and dysmorphic features with negative genetic mutations, not fitting any reported association or syndrome, suggesting the potential existence of a novel disease entity and highlighting the necessity for further exploration into rare genetic conditions for comprehensive patient care and syndrome characterization.
