Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.2709T>G (p.H903Q) alteration is located in exon 22 (coding exon 21) of the MYOM3 gene. This alteration results from a T to G substitution at nucleotide position 2709, causing the histidine (H) at amino acid position 903 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
