Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.55G>T (p.G19C) alteration is located in exon 2 (coding exon 1) of the RMDN3 gene. This alteration results from a G to T substitution at nucleotide position 55, causing the glycine (G) at amino acid position 19 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
