The c.476C>T (p.P159L) alteration is located in exon 4 (coding exon 3) of the TMEM25 gene. This alteration results from a C to T substitution at nucleotide position 476, causing the proline (P) at amino acid position 159 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
