The c.538T>C (p.S180P) alteration is located in exon 1 (coding exon 1) of the YLPM1 gene. This alteration results from a T to C substitution at nucleotide position 538, causing the serine (S) at amino acid position 180 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
