Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 09, 2024The c.2432A>G (p.D811G) alteration is located in exon 15 (coding exon 14) of the SEMA4C gene. This alteration results from a A to G substitution at nucleotide position 2432, causing the aspartic acid (D) at amino acid position 811 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
