Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.345G>C (p.E115D) alteration is located in exon 4 (coding exon 4) of the RIT2 gene. This alteration results from a G to C substitution at nucleotide position 345, causing the glutamic acid (E) at amino acid position 115 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
