The c.1313T>G (p.M438R) alteration is located in exon 4 (coding exon 3) of the ZBTB8B gene. This alteration results from a T to G substitution at nucleotide position 1313, causing the methionine (M) at amino acid position 438 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
