IUGR and IGF abnormalities
Gene: ARCN1Comment on list classification: New gene added by Andžela Lazdāne (Children's Clinical University Hospital of Latvia). This gene is associated with a phenotype in OMIM and Gene2Phenotype (probable). After consulting the Genomics England Clinical Team it was thought that this gene should be Amber on this panel for now as the skeletal phenotype in association with short stature makes the gene better suited to a skeletal panel.Created: 25 Oct 2021, 9:32 a.m. | Last Modified: 25 Oct 2021, 9:32 a.m.

Pathogenic loss-of-function variants in ARCN1 represent an emerging disorder of developmental delay and skeletal manifestations. Phenotype corresponds to IUGR such as craniofacial disorder characterized by facial dysmorphisms, severe micrognathia, rhizomelic shortening, cleft palate, microcephalic dwarfism and mild developmental delay.
