Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 12, 2024The c.512G>A (p.R171Q) alteration is located in exon 5 (coding exon 2) of the KSR1 gene. This alteration results from a G to A substitution at nucleotide position 512, causing the arginine (R) at amino acid position 171 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
