Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1984A>G (p.K662E) alteration is located in exon 21 (coding exon 20) of the ANO4 gene. This alteration results from a A to G substitution at nucleotide position 1984, causing the lysine (K) at amino acid position 662 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
