Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2021The c.49A>G (p.K17E) alteration is located in exon 1 (coding exon 1) of the RTP2 gene. This alteration results from a A to G substitution at nucleotide position 49, causing the lysine (K) at amino acid position 17 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
