Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2022The c.731C>T (p.S244L) alteration is located in exon 6 (coding exon 6) of the SNX8 gene. This alteration results from a C to T substitution at nucleotide position 731, causing the serine (S) at amino acid position 244 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
