Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.1205A>T (p.Q402L) alteration is located in exon 10 (coding exon 10) of the SNX8 gene. This alteration results from a A to T substitution at nucleotide position 1205, causing the glutamine (Q) at amino acid position 402 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
