Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.506G>T (p.G169V) alteration is located in exon 4 (coding exon 4) of the KRR1 gene. This alteration results from a G to T substitution at nucleotide position 506, causing the glycine (G) at amino acid position 169 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
