Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.724C>T (p.R242W) alteration is located in exon 4 (coding exon 2) of the SPSB4 gene. This alteration results from a C to T substitution at nucleotide position 724, causing the arginine (R) at amino acid position 242 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
