Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2023The c.1300C>G (p.Q434E) alteration is located in exon 9 (coding exon 9) of the MYBPH gene. This alteration results from a C to G substitution at nucleotide position 1300, causing the glutamine (Q) at amino acid position 434 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
