Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.480G>C (p.E160D) alteration is located in exon 6 (coding exon 6) of the STX12 gene. This alteration results from a G to C substitution at nucleotide position 480, causing the glutamic acid (E) at amino acid position 160 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
