Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.262G>A (p.V88M) 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 262, causing the valine (V) at amino acid position 88 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
