Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2024The c.3965C>T (p.P1322L) 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 3965, causing the proline (P) at amino acid position 1322 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
