The c.445C>T (p.R149W) alteration is located in exon 4 (coding exon 2) of the AMMECR1L gene. This alteration results from a C to T substitution at nucleotide position 445, causing the arginine (R) at amino acid position 149 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
