Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.782A>G (p.Y261C) alteration is located in exon 3 (coding exon 3) of the SYT16 gene. This alteration results from a A to G substitution at nucleotide position 782, causing the tyrosine (Y) at amino acid position 261 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
