The c.1364G>A (p.R455H) alteration is located in exon 9 (coding exon 9) of the MLLT1 gene. This alteration results from a G to A substitution at nucleotide position 1364, causing the arginine (R) at amino acid position 455 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
