Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_004213.5(SLC28A1):c.167C>T(p.Pro56Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000129 in 1,552,424 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. P56R) has been classified as Uncertain significance.

Ambry Genetics

Feb 21, 2024

The c.167C>T (p.P56L) alteration is located in exon 4 (coding exon 2) of the SLC28A1 gene. This alteration results from a C to T substitution at nucleotide position 167, causing the proline (P) at amino acid position 56 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
