Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.757A>G (p.N253D) alteration is located in exon 9 (coding exon 8) of the ANO4 gene. This alteration results from a A to G substitution at nucleotide position 757, causing the asparagine (N) at amino acid position 253 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
