Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2022The c.927A>T (p.R309S) alteration is located in exon 1 (coding exon 1) of the RGAG4 gene. This alteration results from a A to T substitution at nucleotide position 927, causing the arginine (R) at amino acid position 309 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
