Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2023The c.1127G>T (p.C376F) alteration is located in exon 8 (coding exon 8) of the ACSM1 gene. This alteration results from a G to T substitution at nucleotide position 1127, causing the cysteine (C) at amino acid position 376 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
