Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 29, 2023The c.800A>T (p.K267M) alteration is located in exon 7 (coding exon 7) of the ANKRD13A gene. This alteration results from a A to T substitution at nucleotide position 800, causing the lysine (K) at amino acid position 267 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
