Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 24, 2024The c.436G>A (p.G146R) alteration is located in exon 3 (coding exon 3) of the RSAD1 gene. This alteration results from a G to A substitution at nucleotide position 436, causing the glycine (G) at amino acid position 146 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
