Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2021The c.404G>T (p.C135F) alteration is located in exon 3 (coding exon 2) of the ACSM5 gene. This alteration results from a G to T substitution at nucleotide position 404, causing the cysteine (C) at amino acid position 135 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
