Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 24, 2023The c.1709G>A (p.R570Q) alteration is located in exon 13 (coding exon 13) of the ACSM1 gene. This alteration results from a G to A substitution at nucleotide position 1709, causing the arginine (R) at amino acid position 570 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
