Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.3310C>T (p.R1104W) alteration is located in exon 17 (coding exon 17) of the ANO8 gene. This alteration results from a C to T substitution at nucleotide position 3310, causing the arginine (R) at amino acid position 1104 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
