Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.937C>A (p.H313N) alteration is located in exon 6 (coding exon 6) of the ACSM1 gene. This alteration results from a C to A substitution at nucleotide position 937, causing the histidine (H) at amino acid position 313 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
