The c.515A>G (p.H172R) alteration is located in exon 5 (coding exon 4) of the LCLAT1 gene. This alteration results from a A to G substitution at nucleotide position 515, causing the histidine (H) at amino acid position 172 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
