Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.2308G>A (p.A770T) alteration is located in exon 10 (coding exon 9) of the KANK3 gene. This alteration results from a G to A substitution at nucleotide position 2308, causing the alanine (A) at amino acid position 770 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
