The c.739G>T (p.D247Y) alteration is located in exon 8 (coding exon 7) of the MYLK4 gene. This alteration results from a G to T substitution at nucleotide position 739, causing the aspartic acid (D) at amino acid position 247 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
