Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.3893C>T (p.T1298M) alteration is located in exon 21 (coding exon 20) of the AKNA gene. This alteration results from a C to T substitution at nucleotide position 3893, causing the threonine (T) at amino acid position 1298 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
