Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.10897A>C (p.I3633L) alteration is located in exon 70 (coding exon 70) of the CSMD3 gene. This alteration results from a A to C substitution at nucleotide position 10897, causing the isoleucine (I) at amino acid position 3633 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
