Genes affected

NOP53 (HGNC:4333): (NOP53 ribosome biogenesis factor) Enables 5S rRNA binding activity; identical protein binding activity; and p53 binding activity. Involved in several processes, including negative regulation of transcription, DNA-templated; regulation of cellular protein metabolic process; and regulation of intracellular signal transduction. Located in cytosol; fibrillar center; and nucleoplasm. Colocalizes with rDNA heterochromatin. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.187T>C (p.F63L) alteration is located in exon 1 (coding exon 1) of the GLTSCR2 gene. This alteration results from a T to C substitution at nucleotide position 187, causing the phenylalanine (F) at amino acid position 63 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
