Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.481A>G (p.R161G) alteration is located in exon 4 (coding exon 4) of the KRR1 gene. This alteration results from a A to G substitution at nucleotide position 481, causing the arginine (R) at amino acid position 161 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
