Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.260A>G (p.K87R) alteration is located in exon 2 (coding exon 2) of the ANKRD33 gene. This alteration results from a A to G substitution at nucleotide position 260, causing the lysine (K) at amino acid position 87 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
