Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2023The c.1040A>C (p.K347T) alteration is located in exon 8 (coding exon 8) of the ACTR8 gene. This alteration results from a A to C substitution at nucleotide position 1040, causing the lysine (K) at amino acid position 347 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
