The c.416C>G (p.T139S) alteration is located in exon 5 (coding exon 4) of the MYLK4 gene. This alteration results from a C to G substitution at nucleotide position 416, causing the threonine (T) at amino acid position 139 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
