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]

The c.598G>A (p.V200M) alteration is located in exon 6 (coding exon 6) of the RCL1 gene. This alteration results from a G to A substitution at nucleotide position 598, causing the valine (V) at amino acid position 200 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
