The c.1187T>G (p.L396R) alteration is located in exon 3 (coding exon 2) of the KLF15 gene. This alteration results from a T to G substitution at nucleotide position 1187, causing the leucine (L) at amino acid position 396 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
