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.245T>G (p.F82C) alteration is located in exon 3 (coding exon 2) of the YBEY gene. This alteration results from a T to G substitution at nucleotide position 245, causing the phenylalanine (F) at amino acid position 82 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
