Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 12, 2021 | The c.707G>A (p.R236H) alteration is located in exon 6 (coding exon 6) of the SNX8 gene. This alteration results from a G to A substitution at nucleotide position 707, causing the arginine (R) at amino acid position 236 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
