Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.647G>T (p.R216M) alteration is located in exon 7 (coding exon 6) of the MYLK4 gene. This alteration results from a G to T substitution at nucleotide position 647, causing the arginine (R) at amino acid position 216 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
