Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 18, 2021The c.232G>A (p.D78N) alteration is located in exon 5 (coding exon 5) of the EFCAB3 gene. This alteration results from a G to A substitution at nucleotide position 232, causing the aspartic acid (D) at amino acid position 78 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
