Ambry Genetics

Apr 26, 2024

The c.701T>A (p.L234Q) alteration is located in exon 8 (coding exon 7) of the MYLK4 gene. This alteration results from a T to A substitution at nucleotide position 701, causing the leucine (L) at amino acid position 234 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
