Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2023The c.458G>T (p.R153L) alteration is located in exon 4 (coding exon 3) of the RFPL2 gene. This alteration results from a G to T substitution at nucleotide position 458, causing the arginine (R) at amino acid position 153 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
