Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.2226G>C (p.L742F) alteration is located in exon 3 (coding exon 3) of the SYDE2 gene. This alteration results from a G to C substitution at nucleotide position 2226, causing the leucine (L) at amino acid position 742 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
