Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_152403.4(EGFLAM):c.1996T>G(p.Leu666Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,614,004 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L666F) has been classified as Uncertain significance.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1996T>G (p.L666V) alteration is located in exon 14 (coding exon 14) of the EGFLAM gene. This alteration results from a T to G substitution at nucleotide position 1996, causing the leucine (L) at amino acid position 666 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
