Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 04, 2023The c.893G>A (p.R298Q) alteration is located in exon 8 (coding exon 7) of the SNX25 gene. This alteration results from a G to A substitution at nucleotide position 893, causing the arginine (R) at amino acid position 298 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
