The c.757C>A (p.Q253K) alteration is located in exon 6 (coding exon 6) of the MBIP gene. This alteration results from a C to A substitution at nucleotide position 757, causing the glutamine (Q) at amino acid position 253 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
