Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.647C>T (p.A216V) alteration is located in exon 6 (coding exon 6) of the SNX8 gene. This alteration results from a C to T substitution at nucleotide position 647, causing the alanine (A) at amino acid position 216 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
