Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.2951G>A (p.R984K) alteration is located in exon 10 (coding exon 9) of the KANK4 gene. This alteration results from a G to A substitution at nucleotide position 2951, causing the arginine (R) at amino acid position 984 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
