Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.467G>A (p.S156N) alteration is located in exon 6 (coding exon 6) of the RAB6B gene. This alteration results from a G to A substitution at nucleotide position 467, causing the serine (S) at amino acid position 156 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
