Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.509T>C (p.M170T) alteration is located in exon 3 (coding exon 3) of the ANKRD33 gene. This alteration results from a T to C substitution at nucleotide position 509, causing the methionine (M) at amino acid position 170 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
