Genes affected

PLPBP (HGNC:9457): (pyridoxal phosphate binding protein) This gene encodes a pyridoxal 5'-phosphate binding protein involved in the homeostatic regulation of intracellular pyridoxal 5'-phosphate. This gene has a tumor suppressive effect on hepatocellular carcinoma and other solid tumors of epithelial origin. Naturally occurring mutations in this gene are associated with a pyridoxine-dependent epilepsy. [provided by RefSeq, Mar 2017]

The c.44G>A (p.C15Y) alteration is located in exon 1 (coding exon 1) of the PROSC gene. This alteration results from a G to A substitution at nucleotide position 44, causing the cysteine (C) at amino acid position 15 to be replaced by a tyrosine (Y). The p.C15Y alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
