Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.497G>A (p.S166N) alteration is located in exon 6 (coding exon 4) of the CTTNBP2NL gene. This alteration results from a G to A substitution at nucleotide position 497, causing the serine (S) at amino acid position 166 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
