The c.272G>A (p.R91H) alteration is located in exon 4 (coding exon 3) of the MYLK4 gene. This alteration results from a G to A substitution at nucleotide position 272, causing the arginine (R) at amino acid position 91 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
