The c.1025T>C (p.L342P) alteration is located in exon 10 (coding exon 9) of the MYLK4 gene. This alteration results from a T to C substitution at nucleotide position 1025, causing the leucine (L) at amino acid position 342 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
