Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.82G>A (p.V28I) alteration is located in exon 1 (coding exon 1) of the SCP2D1 gene. This alteration results from a G to A substitution at nucleotide position 82, causing the valine (V) at amino acid position 28 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
