Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.4991C>T (p.A1664V) alteration is located in exon 35 (coding exon 33) of the MYH4 gene. This alteration results from a C to T substitution at nucleotide position 4991, causing the alanine (A) at amino acid position 1664 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
