Nov 10, 2022

The c.698A>G (p.K233R) alteration is located in exon 5 (coding exon 5) of the PLBD1 gene. This alteration results from a A to G substitution at nucleotide position 698, causing the lysine (K) at amino acid position 233 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
