Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.670A>T (p.T224S) alteration is located in exon 8 (coding exon 7) of the ANO4 gene. This alteration results from a A to T substitution at nucleotide position 670, causing the threonine (T) at amino acid position 224 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
