Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 30, 2024The c.98A>G (p.D33G) alteration is located in exon 1 (coding exon 1) of the SYT16 gene. This alteration results from a A to G substitution at nucleotide position 98, causing the aspartic acid (D) at amino acid position 33 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
