The c.1172T>C (p.L391P) alteration is located in exon 10 (coding exon 9) of the TCAIM gene. This alteration results from a T to C substitution at nucleotide position 1172, causing the leucine (L) at amino acid position 391 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
