Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.1475G>A (p.R492Q) alteration is located in exon 16 (coding exon 15) of the ANO4 gene. This alteration results from a G to A substitution at nucleotide position 1475, causing the arginine (R) at amino acid position 492 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
