Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 17, 2023The c.885C>A (p.F295L) alteration is located in exon 7 (coding exon 7) of the SNX8 gene. This alteration results from a C to A substitution at nucleotide position 885, causing the phenylalanine (F) at amino acid position 295 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
