Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 01, 2024The c.130T>G (p.C44G) alteration is located in exon 3 (coding exon 1) of the BEX1 gene. This alteration results from a T to G substitution at nucleotide position 130, causing the cysteine (C) at amino acid position 44 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
