Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 15, 2021The c.1220G>A (p.C407Y) alteration is located in exon 6 (coding exon 6) of the SPRED2 gene. This alteration results from a G to A substitution at nucleotide position 1220, causing the cysteine (C) at amino acid position 407 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
