Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.10358A>G (p.D3453G) alteration is located in exon 68 (coding exon 68) of the CSMD1 gene. This alteration results from a A to G substitution at nucleotide position 10358, causing the aspartic acid (D) at amino acid position 3453 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
