Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.10363T>G (p.S3455A) alteration is located in exon 65 (coding exon 65) of the CSMD3 gene. This alteration results from a T to G substitution at nucleotide position 10363, causing the serine (S) at amino acid position 3455 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
