The c.623C>T (p.T208I) alteration is located in exon 5 (coding exon 4) of the RCN3 gene. This alteration results from a C to T substitution at nucleotide position 623, causing the threonine (T) at amino acid position 208 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
