Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.1324A>C (p.K442Q) alteration is located in exon 12 (coding exon 11) of the RMDN3 gene. This alteration results from a A to C substitution at nucleotide position 1324, causing the lysine (K) at amino acid position 442 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
