Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 27, 2022The c.5681A>T (p.N1894I) alteration is located in exon 40 (coding exon 38) of the MYH4 gene. This alteration results from a A to T substitution at nucleotide position 5681, causing the asparagine (N) at amino acid position 1894 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
