We describe a stillborn female with acrofacial dysostosis and frontonasal dysplasia. She had protrusion of the forehead, with marked hypertelorism and absence of the nose but with the rhinencephalon present. Autopsy showed wide cranial sutures, severe hydrocephalus with separation of the right and left hemispheres of the brain, preservation of the olfactory bulb and first and second cranial nerves. The child also had small kidneys bilaterally, rectal atresia and an absent anus with rectovaginal fistula. These clinical findings suggest a new form of acrofacial dysostosis.

Dihydroorotate dehydrogenase (DHODH) catalyzes the fourth enzymatic reaction of the pyrimidine biosynthesis pathway. Miller syndrome, also known as postaxial acrofacial dysostosis, is caused by biallelic pathogenic variants in . We present a patient with a relatively mild skeletal phenotype carrying a novel variant of unknown significance in : c.

Article Synopsis
- - Baller-Gerold syndrome, RAPADILINO syndrome, and Rothmund-Thomson syndrome, which are linked to mutations in the RECQL4 gene, exhibit autosomal recessive inheritance and are often identified in infants and children.
- - Recent findings revealed two fetuses with severe structural abnormalities caused by biallelic RECQL4 variants during the perinatal period, such as underdeveloped forearms and legs, and one case involving significant lung issues.
- - One fetus tragically died due to respiratory failure, while the other pregnancy was terminated; the variants were confirmed through genetic sequencing techniques.

Background: Ellis-van Creveld syndrome (EvC) is a recessive disorder characterised by acromesomelic limb shortening, postaxial polydactyly, nail-teeth dysplasia and congenital cardiac defects, primarily caused by pathogenic variants in or . Weyers acrofacial dysostosis (WAD) is an ultra-rare dominant condition allelic to EvC. The present work aimed to enhance current knowledge on the clinical manifestations of EvC and WAD and broaden their mutational spectrum.

Nager syndrome (NS) is a rare acrofacial dysostosis caused by heterozygous loss-of-function variants in the splicing factor 3B subunit 4 (SF3B4). The main clinical features of patients with NS are characterized by facial-mandibular and preaxial limb malformations. The migration and specification of neural crest cells are crucial for craniofacial development, and mitochondrial fitness appears to play a role in such processes.

Weyers acrofacial dysostosis (WAD) is a rare skeletal dysplasia, which is autosomal-dominant, and the clinical symptoms are presented as dental anomalies, polydactyly, nail dystrophy, and short physical stature. It is also termed "Curry‑Hall syndrome" and reported to be linked to genetic mutations mapped on chromosome 4p16, the region reported being commonly associated with a similar genetic syndrome, Ellis-van Creveld (EVC) syndrome. Most individuals with EVC have congenital heart abnormalities, most often atrial septal defects, unlike WAD.
