Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2022The c.1210G>A (p.D404N) alteration is located in exon 9 (coding exon 9) of the SPNS1 gene. This alteration results from a G to A substitution at nucleotide position 1210, causing the aspartic acid (D) at amino acid position 404 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
