Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_001013631.3(HNRNPCL1):c.500G>A(p.Arg167Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000187 in 1,606,328 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/20 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. R167P) has been classified as Uncertain significance.

The c.500G>A (p.R167Q) alteration is located in exon 2 (coding exon 1) of the HNRNPCL1 gene. This alteration results from a G to A substitution at nucleotide position 500, causing the arginine (R) at amino acid position 167 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
