The c.267G>T (p.M89I) alteration is located in exon 3 (coding exon 3) of the LCNL1 gene. This alteration results from a G to T substitution at nucleotide position 267, causing the methionine (M) at amino acid position 89 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
