The c.743G>A (p.R248Q) alteration is located in exon 6 (coding exon 4) of the MTCL1 gene. This alteration results from a G to A substitution at nucleotide position 743, causing the arginine (R) at amino acid position 248 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
