Collection Method: clinical testing

The c.5354G>A (p.R1785Q) alteration is located in exon 37 (coding exon 35) of the MYH13 gene. This alteration results from a G to A substitution at nucleotide position 5354, causing the arginine (R) at amino acid position 1785 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
