Ambry Genetics

Dec 30, 2023

The c.278T>C (p.L93P) alteration is located in exon 2 (coding exon 2) of the KLF17 gene. This alteration results from a T to C substitution at nucleotide position 278, causing the leucine (L) at amino acid position 93 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
