Genes affected
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.331G>C (p.V111L) alteration is located in exon 3 (coding exon 2) of the YBEY gene. This alteration results from a G to C substitution at nucleotide position 331, causing the valine (V) at amino acid position 111 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
