Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.3823C>T (p.R1275C) alteration is located in exon 24 (coding exon 24) of the CNTNAP3B gene. This alteration results from a C to T substitution at nucleotide position 3823, causing the arginine (R) at amino acid position 1275 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
