The c.5731G>A (p.A1911T) alteration is located in exon 40 (coding exon 38) of the MYH13 gene. This alteration results from a G to A substitution at nucleotide position 5731, causing the alanine (A) at amino acid position 1911 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
