Genes affected

TYSND1 (HGNC:28531): (trypsin like peroxisomal matrix peptidase 1) This gene encodes a protease that removes the N-terminal peroxisomal targeting signal (PTS2) from proteins produced in the cytosol, thereby facilitating their import into the peroxisome. The encoded protein is also capable of removing the C-terminal peroxisomal targeting signal (PTS1) from proteins in the peroxisomal matrix. The full-length protein undergoes self-cleavage to produce shorter, potentially inactive, peptides. Alternative splicing results in multiple transcript variants for this gene.

The c.1433G>C (p.S478T) alteration is located in exon 3 (coding exon 3) of the TYSND1 gene. This alteration results from a G to C substitution at nucleotide position 1433, causing the serine (S) at amino acid position 478 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
