The c.1072C>T (p.H358Y) alteration is located in exon 11 (coding exon 10) of the MYLK4 gene. This alteration results from a C to T substitution at nucleotide position 1072, causing the histidine (H) at amino acid position 358 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
