Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2024The c.677C>T (p.T226M) alteration is located in exon 5 (coding exon 5) of the ANKRD33 gene. This alteration results from a C to T substitution at nucleotide position 677, causing the threonine (T) at amino acid position 226 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
