Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.1102G>T (p.V368L) alteration is located in exon 6 (coding exon 4) of the CTTNBP2NL gene. This alteration results from a G to T substitution at nucleotide position 1102, causing the valine (V) at amino acid position 368 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
