Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.2053C>T (p.R685C) alteration is located in exon 6 (coding exon 6) of the SPTY2D1 gene. This alteration results from a C to T substitution at nucleotide position 2053, causing the arginine (R) at amino acid position 685 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
