Genes affected

ART5 (HGNC:24049): (ADP-ribosyltransferase 5) The protein encoded by this gene belongs to the ARG-specific ADP-ribosyltransferase family. Proteins in this family regulate the function of target proteins by attaching ADP-ribose to specific amino acid residues in their target proteins. The mouse homolog lacks a glycosylphosphatidylinositol-anchor signal sequence and is predicted to be a secretory enzyme. Several transcripts encoding different isoforms have been found for this gene.

The c.191T>C (p.L64P) alteration is located in exon 2 (coding exon 2) of the ART5 gene. This alteration results from a T to C substitution at nucleotide position 191, causing the leucine (L) at amino acid position 64 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
