Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 05, 2023The c.368G>A (p.R123H) alteration is located in exon 4 (coding exon 3) of the SUSD4 gene. This alteration results from a G to A substitution at nucleotide position 368, causing the arginine (R) at amino acid position 123 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
