The c.230A>C (p.H77P) alteration is located in exon 1 (coding exon 1) of the KLF16 gene. This alteration results from a A to C substitution at nucleotide position 230, causing the histidine (H) at amino acid position 77 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
