Jul 09, 2021

The c.128C>T (p.P43L) alteration is located in exon 3 (coding exon 1) of the EXD2 gene. This alteration results from a C to T substitution at nucleotide position 128, causing the proline (P) at amino acid position 43 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
