The c.851T>C (p.M284T) alteration is located in exon 1 (coding exon 1) of the ACTBL2 gene. This alteration results from a T to C substitution at nucleotide position 851, causing the methionine (M) at amino acid position 284 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
