The c.1089T>A (p.H363Q) alteration is located in exon 1 (coding exon 1) of the MAS1L gene. This alteration results from a T to A substitution at nucleotide position 1089, causing the histidine (H) at amino acid position 363 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
