The c.596T>C (p.L199P) alteration is located in exon 1 (coding exon 1) of the TMEM115 gene. This alteration results from a T to C substitution at nucleotide position 596, causing the leucine (L) at amino acid position 199 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
