Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.1045C>T (p.P349S) alteration is located in exon 7 (coding exon 7) of the ACSM1 gene. This alteration results from a C to T substitution at nucleotide position 1045, causing the proline (P) at amino acid position 349 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
