Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_024301.5(FKRP):āc.11C>Gā(p.Thr4Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000716 in 1,606,848 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T4A) has been classified as Uncertain significance.

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 29, 2023 | The p.T4S variant (also known as c.11C>G), located in coding exon 1 of the FKRP gene, results from a C to G substitution at nucleotide position 11. The threonine at codon 4 is replaced by serine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species; however, serine is the reference amino acid in other vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
Walker-Warburg congenital muscular dystrophy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 13, 2022 | This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 4 of the FKRP protein (p.Thr4Ser). This variant is present in population databases (rs771333733, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with FKRP-related conditions. ClinVar contains an entry for this variant (Variation ID: 290603). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt FKRP protein function. 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. - |
