The c.5123A>G (p.Q1708R) alteration is located in exon 35 (coding exon 33) of the MYH4 gene. This alteration results from a A to G substitution at nucleotide position 5123, causing the glutamine (Q) at amino acid position 1708 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
