Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2023The c.3377C>T (p.T1126I) alteration is located in exon 16 (coding exon 15) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 3377, causing the threonine (T) at amino acid position 1126 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
