Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 15, 2021The c.1016A>C (p.E339A) alteration is located in exon 9 (coding exon 7) of the ACSM2B gene. This alteration results from a A to C substitution at nucleotide position 1016, causing the glutamic acid (E) at amino acid position 339 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
