Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.466C>G (p.R156G) alteration is located in exon 4 (coding exon 4) of the R3HDM4 gene. This alteration results from a C to G substitution at nucleotide position 466, causing the arginine (R) at amino acid position 156 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
