This report concerns two new cases of the Cohen syndrome and gives further information on the variable phenotypical pattern of the disease. The frequency of major and minor clinical signs is reviewed from all the published reports. Among the minor signs we found previously undescribed skeletal abnormalities in one of our patients. The reported delay onset of puberty, which appears to be a frequent aspect of the syndrome, seems to occur without LH and FSH deficiency, as our patients show.

Congenital neutropenia (CoN) is a heterogeneous group of inborn errors of immunity (IEI) characterized by recurrent infections and early onset of neutropenia (NP). This study aimed to investigate the demographic and clinical data of children with CoN and idiopathic neutropenia (IN) in Morocco. We performed a retrospective study of patients with CoN and analyzed the clinical and laboratory findings of patients with CoN and IN diagnosed between 1999 and 2018 in a clinical immunology unit of a large pediatric hospital.

Retinitis pigmentosa (RP) is a progressive inherited retinal dystrophy, characterized by the degeneration of photoreceptors, presenting as a rod-cone dystrophy. Approximately 20-30% of patients with RP also exhibit extra-ocular manifestations in the context of a syndrome. This manuscript discusses the broad spectrum of syndromes associated with RP, pathogenic mechanisms, clinical manifestations, differential diagnoses, clinical management approaches, and future perspectives.

Introduction: Cohen syndrome (CS) is an early-onset pediatric neurodevelopmental disorder characterized by postnatal microcephaly and intellectual disability. An accurate diagnosis for individuals with CS is crucial, particularly for their caretakers and future prospects. CS is predominantly caused by rare homozygous or compound heterozygous pathogenic variants in the vacuolar protein sorting-associated 13B () gene, which disrupt protein translation and lead to a loss of function (LoF) of the encoded VPS13B protein.
