Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2024The c.1459C>T (p.R487W) alteration is located in exon 3 (coding exon 3) of the SPTY2D1 gene. This alteration results from a C to T substitution at nucleotide position 1459, causing the arginine (R) at amino acid position 487 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
