Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 19, 2024The c.127G>A (p.A43T) alteration is located in exon 2 (coding exon 1) of the RAB3D gene. This alteration results from a G to A substitution at nucleotide position 127, causing the alanine (A) at amino acid position 43 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
