Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.317A>T (p.D106V) alteration is located in exon 4 (coding exon 4) of the RAB40B gene. This alteration results from a A to T substitution at nucleotide position 317, causing the aspartic acid (D) at amino acid position 106 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
