Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2022The c.314C>T (p.T105M) alteration is located in exon 3 (coding exon 3) of the NECAB2 gene. This alteration results from a C to T substitution at nucleotide position 314, causing the threonine (T) at amino acid position 105 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
