Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 18, 2024The c.338G>A (p.R113K) alteration is located in exon 2 (coding exon 2) of the RTP3 gene. This alteration results from a G to A substitution at nucleotide position 338, causing the arginine (R) at amino acid position 113 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
