Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2022The c.1264G>C (p.D422H) alteration is located in exon 1 (coding exon 1) of the RGAG4 gene. This alteration results from a G to C substitution at nucleotide position 1264, causing the aspartic acid (D) at amino acid position 422 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
