Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 19, 2024The c.2677A>C (p.M893L) alteration is located in exon 14 (coding exon 14) of the ABTB2 gene. This alteration results from a A to C substitution at nucleotide position 2677, causing the methionine (M) at amino acid position 893 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
