Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 1P and 2B. PP2BP4_Moderate
The NM_198586.3(NHLRC1):c.107G>C(p.Arg36Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000257 in 1,597,278 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 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. R36Q) has been classified as Uncertain significance.

Lafora disease Uncertain:1
This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 36 of the NHLRC1 protein (p.Arg36Pro). This variant is present in population databases (rs764691077, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with NHLRC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 571831). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Inborn genetic diseases Uncertain:1
The c.107G>C (p.R36P) alteration is located in exon 1 (coding exon 1) of the NHLRC1 gene. This alteration results from a G to C substitution at nucleotide position 107, causing the arginine (R) at amino acid position 36 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
