Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 05, 2021The c.917A>T (p.D306V) alteration is located in exon 10 (coding exon 9) of the MYLK4 gene. This alteration results from a A to T substitution at nucleotide position 917, causing the aspartic acid (D) at amino acid position 306 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
