Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2022The c.847G>A (p.E283K) alteration is located in exon 10 (coding exon 7) of the KSR1 gene. This alteration results from a G to A substitution at nucleotide position 847, causing the glutamic acid (E) at amino acid position 283 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
