The c.430G>T (p.V144L) alteration is located in exon 2 (coding exon 2) of the EEFSEC gene. This alteration results from a G to T substitution at nucleotide position 430, causing the valine (V) at amino acid position 144 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
