Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.578G>A (p.G193D) alteration is located in exon 2 (coding exon 2) of the RTP2 gene. This alteration results from a G to A substitution at nucleotide position 578, causing the glycine (G) at amino acid position 193 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
