The c.47G>T (p.C16F) alteration is located in exon 1 (coding exon 1) of the SCGB2B2 gene. This alteration results from a G to T substitution at nucleotide position 47, causing the cysteine (C) at amino acid position 16 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
