Collection Method: clinical testing

The c.1319A>G (p.D440G) alteration is located in exon 9 (coding exon 9) of the PLBD1 gene. This alteration results from a A to G substitution at nucleotide position 1319, causing the aspartic acid (D) at amino acid position 440 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
