The c.3220A>G (p.T1074A) alteration is located in exon 29 (coding exon 29) of the MCF2L2 gene. This alteration results from a A to G substitution at nucleotide position 3220, causing the threonine (T) at amino acid position 1074 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
