The c.953T>A (p.M318K) alteration is located in exon 2 (coding exon 1) of the ZBTB8B gene. This alteration results from a T to A substitution at nucleotide position 953, causing the methionine (M) at amino acid position 318 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
