Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.514C>T (p.R172C) alteration is located in exon 4 (coding exon 4) of the SPNS3 gene. This alteration results from a C to T substitution at nucleotide position 514, causing the arginine (R) at amino acid position 172 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
