Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_004213.5(SLC28A1):c.377G>A(p.Arg126His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000118 in 1,613,722 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 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. R126C) has been classified as Uncertain significance.

The c.377G>A (p.R126H) alteration is located in exon 6 (coding exon 4) of the SLC28A1 gene. This alteration results from a G to A substitution at nucleotide position 377, causing the arginine (R) at amino acid position 126 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
