Genetic Variant SLC43A1:p.Arg536Gln (chr11-57485169-C-T) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

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

The NM_003627.6(SLC43A1):c.1607G>A(p.Arg536Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000123 in 1,614,036 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. R536W) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.1607G>A (p.R536Q) alteration is located in exon 15 (coding exon 14) of the SLC43A1 gene. This alteration results from a G to A substitution at nucleotide position 1607, causing the arginine (R) at amino acid position 536 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
