Jan 23, 2024

The c.497C>T (p.T166I) alteration is located in exon 6 (coding exon 6) of the NECAB2 gene. This alteration results from a C to T substitution at nucleotide position 497, causing the threonine (T) at amino acid position 166 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
