The c.666T>A (p.N222K) alteration is located in exon 6 (coding exon 5) of the LCLAT1 gene. This alteration results from a T to A substitution at nucleotide position 666, causing the asparagine (N) at amino acid position 222 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
