Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2024The c.1484C>T (p.A495V) alteration is located in exon 11 (coding exon 11) of the ACSM1 gene. This alteration results from a C to T substitution at nucleotide position 1484, causing the alanine (A) at amino acid position 495 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
