Genes affected

RCL1 (HGNC:17687): (RNA terminal phosphate cyclase like 1) Predicted to enable endoribonuclease activity. Predicted to be involved in endonucleolytic cleavage of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to act upstream of or within endonucleolytic cleavage in 5'-ETS of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and endonucleolytic cleavage in ITS1 to separate SSU-rRNA from 5.8S rRNA and LSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA). Predicted to be located in nucleoplasm. Predicted to be active in nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

ENST00000381750.4:c.370C>T, p.Gln124Ter, 370/1122 results in a premature truncation of the protein and thus scored as Pathogenic using ACMG criteria. It is absent from controls. However, there are limited functional studies on RCL1 at this time and the carrier father has a less severe behavioral phenotype. -
