Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2024The c.1691T>C (p.I564T) alteration is located in exon 13 (coding exon 13) of the ACSM1 gene. This alteration results from a T to C substitution at nucleotide position 1691, causing the isoleucine (I) at amino acid position 564 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
