Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.757C>T (p.R253W) alteration is located in exon 3 (coding exon 3) of the SYT16 gene. This alteration results from a C to T substitution at nucleotide position 757, causing the arginine (R) at amino acid position 253 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
