Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 08, 2024The c.337G>A (p.V113I) alteration is located in exon 3 (coding exon 3) of the SPCS2 gene. This alteration results from a G to A substitution at nucleotide position 337, causing the valine (V) at amino acid position 113 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
