The c.677C>T (p.P226L) alteration is located in exon 9 (coding exon 6) of the INCA1 gene. This alteration results from a C to T substitution at nucleotide position 677, causing the proline (P) at amino acid position 226 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
