Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.557G>A (p.S186N) alteration is located in exon 6 (coding exon 6) of the NECAB2 gene. This alteration results from a G to A substitution at nucleotide position 557, causing the serine (S) at amino acid position 186 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
