Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 15, 2021The c.514C>A (p.L172I) alteration is located in exon 4 (coding exon 3) of the CDKL2 gene. This alteration results from a C to A substitution at nucleotide position 514, causing the leucine (L) at amino acid position 172 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
