Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 14, 2022 | The c.533G>T (p.R178L) alteration is located in exon 1 (coding exon 1) of the ACTBL2 gene. This alteration results from a G to T substitution at nucleotide position 533, causing the arginine (R) at amino acid position 178 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
