Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 25, 2023The c.625A>G (p.I209V) alteration is located in exon 1 (coding exon 1) of the ACTBL2 gene. This alteration results from a A to G substitution at nucleotide position 625, causing the isoleucine (I) at amino acid position 209 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
