Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM2PP3_StrongPP5_Very_Strong
The NM_001127898.4(CLCN5):c.941C>T(p.Ser314Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000915 in 1,093,248 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 1 hemizygotes in GnomAD. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. S314S) has been classified as Benign.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 18, 2023 | This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 244 of the CLCN5 protein (p.Ser244Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Dent disease (PMID: 19546591, 24081861, 27117801, 28580211, 31672324). ClinVar contains an entry for this variant (Variation ID: 11802). 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 disruptive. Experimental studies have shown that this missense change affects CLCN5 function (PMID: 8559248, 27117801). For these reasons, this variant has been classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Nov 18, 2020 | Reported previously in multiple unrelated individuals with CLCN5-related disorders referred for genetic testing at GeneDx and in the published literature (Sekine et al. 2014; Wu et al. 2009); Published functional and expression studies of the S244L variant show that its presence reduces the current of the CLCN5 chloride channel and significantly impairs CLCN5 transport function (Lloyd et al., 1996; Grand et al., 2011; Tang et al., 2016); Not observed in large population cohorts (Lek et al., 2016); Missense variants in this gene are often considered pathogenic (Stenson et al., 2014); This variant is associated with the following publications: (PMID: 22083641, 28580211, 8559248, 20804101, 21305656, 24081861, 19546591, 21955393, 27117801, 31672324, 31852738, 31674016, 9187673, 32393202) - |

CLCN5-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Aug 23, 2023 | The CLCN5 c.731C>T variant is predicted to result in the amino acid substitution p.Ser244Leu. This variant was reported in many individuals with Dent disease (Tang et al. 2016. PubMed ID: 27117801; Hureaux et al. 2019. PubMed ID: 31672324; Sekine et al. 2013. PubMed ID: 24081861), and was confirmed de novo in one Dent disease patient (Ye et al. 2020. PubMed ID: 31674016). This variant was also reported in two families with x-linked recessive hypophosphatemic rickets (Lloyd et al. 1996. PubMed ID: 8559248; Oudet et al. 1997. PubMed ID: 9187673). Experimental studies suggest this variant impacts protein function (Grand et al. 2011. PubMed ID: 21305656; Lourdel et al. 2011. PubMed ID: 22083641). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. This variant is interpreted as pathogenic. - |
