Collection Method: clinical testing

The c.569G>A (p.R190Q) alteration is located in exon 5 (coding exon 5) of the ATP5SL gene. This alteration results from a G to A substitution at nucleotide position 569, causing the arginine (R) at amino acid position 190 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
