The c.974G>A (p.R325Q) alteration is located in exon 10 (coding exon 10) of the TOM1L1 gene. This alteration results from a G to A substitution at nucleotide position 974, causing the arginine (R) at amino acid position 325 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
