Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.278A>C (p.D93A) alteration is located in exon 1 (coding exon 1) of the EXOC3L4 gene. This alteration results from a A to C substitution at nucleotide position 278, causing the aspartic acid (D) at amino acid position 93 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
