The c.5093G>A (p.R1698Q) alteration is located in exon 41 (coding exon 41) of the MYO5C gene. This alteration results from a G to A substitution at nucleotide position 5093, causing the arginine (R) at amino acid position 1698 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
