Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.775C>T (p.R259W) alteration is located in exon 6 (coding exon 5) of the SUSD4 gene. This alteration results from a C to T substitution at nucleotide position 775, causing the arginine (R) at amino acid position 259 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
