Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 18, 2022The c.1126A>G (p.M376V) alteration is located in exon 10 (coding exon 8) of the ACSM2B gene. This alteration results from a A to G substitution at nucleotide position 1126, causing the methionine (M) at amino acid position 376 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
