NM_201384.3:c.10835G>A
Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBS1_Supporting
The NM_201384.3(PLEC):c.10835G>A(p.Arg3612Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000863 in 1,611,134 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 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. R3612W) has been classified as Uncertain significance.

Variant summary: PLEC c.10916G>A (p.Arg3639Gln) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function all suggest that this variant is likely to be tolerated. The variant allele was found at a frequency of 9.3e-05 in 247054 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in PLEC causing Epidermolysis bullosa simplex 5C, with pyloric atresia (9.3e-05 vs 0.0061), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.10916G>A in individuals affected with PLEC-related disorders and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 285678). Based on the evidence outlined above, the variant was classified as uncertain significance. -
Inborn genetic diseases    Uncertain:1 
The c.10916G>A (p.R3639Q) alteration is located in exon 33 (coding exon 32) of the PLEC gene. This alteration results from a G to A substitution at nucleotide position 10916, causing the arginine (R) at amino acid position 3639 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 3639 of the PLEC protein (p.Arg3639Gln). This variant is present in population databases (rs369226598, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PLEC-related conditions. ClinVar contains an entry for this variant (Variation ID: 285678). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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. -
