Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 11, 2023The c.460T>C (p.F154L) alteration is located in exon 2 (coding exon 2) of the RMDN2 gene. This alteration results from a T to C substitution at nucleotide position 460, causing the phenylalanine (F) at amino acid position 154 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
