Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.1555C>T (p.P519S) alteration is located in exon 12 (coding exon 12) of the ACSM1 gene. This alteration results from a C to T substitution at nucleotide position 1555, causing the proline (P) at amino acid position 519 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
