Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.1097C>T (p.P366L) alteration is located in exon 9 (coding exon 9) of the SNX8 gene. This alteration results from a C to T substitution at nucleotide position 1097, causing the proline (P) at amino acid position 366 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
