The c.1223T>C (p.L408P) alteration is located in exon 12 (coding exon 12) of the TMEM161A gene. This alteration results from a T to C substitution at nucleotide position 1223, causing the leucine (L) at amino acid position 408 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
