Two sisters from a Lebanese family presented with slight developmental delay, short stature, congenital microcephaly, frontal bossing, mild hyperplastic supra-orbital ridges, broad nasal root, small dysplastic low-set ears, high arched palate, short neck, and hearing impairment. In addition, the oldest affected sister had esophageal atresia and the other sister had cleft palate. Temporal bone abnormalities included hypoplasia of the external auditory canal, small middle ear cavity, abnormal ossicles, and inner ear malformations with enlarged vestibular acqueducts. Differential diagnosis is discussed, and the possibility of a newly recognized autosomal recessive syndrome is raised.

Cystic kidney diseases (CyKD) are a diverse group of disorders affecting more than 1 in 1000 individuals. Over 120 genes are implicated, primarily encoding components of the primary cilium, transcription factors, and morphogens. Prognosis varies greatly by molecular diagnosis.

Nicotinamide adenine dinucleotide phosphate hydrate dehydratase (NAXD) and nicotinamide adenine dinucleotide phosphate hydrate epimerase (NAXE) deficiencies are rare autosomal recessive metabolic disorders characterized by severe neurological manifestations during infancy. In affected individuals, febrile illnesses can trigger progressive encephalopathy often accompanied by distinctive skin eruptions, resulting in high mortality rates. This study reviews the literature on NAXD/NAXE deficiencies, focusing on dermatological manifestations and their correlation with genotypic variations and treatment responses.

Aagenaes syndrome, also known as lymphoedema cholestasis syndrome 1 (LCS1), is a rare autosomal recessive disorder characterized by neonatal cholestasis and chronic lymphedema, primarily affecting the lower extremities. The genetic basis for this syndrome was recently linked to a variant in the 5'-untranslated region (5'-UTR) of the UNC45A gene, located on chromosome 15q. This study aimed to identify the genetic mutations associated with Aagenaes syndrome in two siblings and to explore their clinical implications.

Objectives: Wilson's disease (WD) is a rare autosomal recessive inherited disorder characterized by dysregulated copper metabolism, amenable to treatment with chelating agents. It manifests with hepatic and neurological symptoms, often precipitating the development of liver cirrhosis as a prominent complication. This study aims to elucidate the factors, biomarker alterations, and therapeutic modalities influencing the progression of cirrhosis in WD patients.

Cartilage‑hair hypoplasia (CHH) is an autosomal recessive form of metaphyseal chondrodysplasia caused by RNA component of mitochondrial RNA processing endoribonuclease (RMRP) gene variants; however, its molecular etiology remains unclear. Whole‑exome sequencing was performed to detect possible pathogenic variants in a patient with a typical short stature and sparse hair. A co‑segregation analysis was also conducted and variants in the family members of the patient were confirmed by Sanger sequencing.
