Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 25, 2023The c.355G>A (p.V119I) alteration is located in exon 5 (coding exon 5) of the RAB40B gene. This alteration results from a G to A substitution at nucleotide position 355, causing the valine (V) at amino acid position 119 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
