Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2022The c.831T>G (p.C277W) alteration is located in exon 10 (coding exon 10) of the SNX31 gene. This alteration results from a T to G substitution at nucleotide position 831, causing the cysteine (C) at amino acid position 277 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
