Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.722A>C (p.Y241S) alteration is located in exon 1 (coding exon 1) of the ACTBL2 gene. This alteration results from a A to C substitution at nucleotide position 722, causing the tyrosine (Y) at amino acid position 241 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
