Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.56C>T (p.T19M) alteration is located in exon 1 (coding exon 1) of the ACTL8 gene. This alteration results from a C to T substitution at nucleotide position 56, causing the threonine (T) at amino acid position 19 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
