Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2022The c.65A>G (p.K22R) alteration is located in exon 1 (coding exon 1) of the KRR1 gene. This alteration results from a A to G substitution at nucleotide position 65, causing the lysine (K) at amino acid position 22 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
