not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024The c.1133G>A (p.R378H) alteration is located in exon 12 (coding exon 11) of the MYLK4 gene. This alteration results from a G to A substitution at nucleotide position 1133, causing the arginine (R) at amino acid position 378 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
