The c.1244G>C (p.S415T) alteration is located in exon 8 (coding exon 8) of the BBOF1 gene. This alteration results from a G to C substitution at nucleotide position 1244, causing the serine (S) at amino acid position 415 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
