Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.10928T>C (p.I3643T) alteration is located in exon 70 (coding exon 70) of the CSMD3 gene. This alteration results from a T to C substitution at nucleotide position 10928, causing the isoleucine (I) at amino acid position 3643 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
