The c.304G>A (p.D102N) alteration is located in exon 5 (coding exon 4) of the TOMM40L gene. This alteration results from a G to A substitution at nucleotide position 304, causing the aspartic acid (D) at amino acid position 102 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
