Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 29, 2024The c.593G>A (p.R198H) alteration is located in exon 8 (coding exon 7) of the RFX8 gene. This alteration results from a G to A substitution at nucleotide position 593, causing the arginine (R) at amino acid position 198 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
