Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 10, 2024The c.773C>T (p.P258L) 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 773, causing the proline (P) at amino acid position 258 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
