Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2022The c.3913G>A (p.G1305R) alteration is located in exon 27 (coding exon 27) of the SNED1 gene. This alteration results from a G to A substitution at nucleotide position 3913, causing the glycine (G) at amino acid position 1305 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
