Dec 31, 2023

The c.601G>A (p.V201I) alteration is located in exon 7 (coding exon 6) of the SPC25 gene. This alteration results from a G to A substitution at nucleotide position 601, causing the valine (V) at amino acid position 201 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
