YBEY (HGNC:1299): (ybeY metalloendoribonuclease) This gene encodes a highly conserved metalloprotein. A similar protein in bacteria acts as an endoribonuclease, and is thought to function in ribosomal RNA maturation and ribosome assembly. Alternative splicing results in multiple transcript variants.

The c.911C>T (p.P304L) alteration is located in exon 8 (coding exon 8) of the C21orf58 gene. This alteration results from a C to T substitution at nucleotide position 911, causing the proline (P) at amino acid position 304 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
