Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.298G>T (p.V100L) alteration is located in exon 2 (coding exon 2) of the SNED1 gene. This alteration results from a G to T substitution at nucleotide position 298, causing the valine (V) at amino acid position 100 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
