Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.466G>A (p.G156S) alteration is located in exon 6 (coding exon 5) of the RFX8 gene. This alteration results from a G to A substitution at nucleotide position 466, causing the glycine (G) at amino acid position 156 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
