Collection Method: clinical testing

The c.227A>T (p.K76I) alteration is located in exon 2 (coding exon 2) of the JDP2 gene. This alteration results from a A to T substitution at nucleotide position 227, causing the lysine (K) at amino acid position 76 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
