The c.883A>G (p.T295A) alteration is located in exon 7 (coding exon 6) of the LCLAT1 gene. This alteration results from a A to G substitution at nucleotide position 883, causing the threonine (T) at amino acid position 295 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
