Variant summary

Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1 PM2 PM5 PP3_Strong PP5_Very_Strong

The NM_003672.4(CDC14A):​c.934C>G​(p.Arg312Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000685 in 1,460,838 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R312Q) has been classified as Likely pathogenic.

Genes affected

CDC14A (HGNC:1718): (cell division cycle 14A) The protein encoded by this gene is a member of the dual specificity protein tyrosine phosphatase family. It is highly similar to Saccharomyces cerevisiae Cdc14, a protein tyrosine phosphatase involved in the exit of cell mitosis and initiation of DNA replication, suggesting a role in cell cycle control. This protein has been shown to interact with, and dephosphorylate tumor suppressor protein p53, and is thought to regulate the function of p53. Alternative splicing of this gene results in several transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PM1: In a domain Tyrosine-protein phosphatase (size 157) in uniprot entity CC14A_HUMAN there are 7 pathogenic changes around while only 2 benign (78%) in NM_003672.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr1-100468052-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 559435.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.943
• PP5: Variant 1-100468051-C-G is Pathogenic according to our data. Variant chr1-100468051-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 559436.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-100468051-C-G is described in Lovd as [Pathogenic].

Autosomal recessive nonsyndromic hearing loss 32 Pathogenic:2

Likely pathogenic, criteria provided, single submitter	curation	SIB Swiss Institute of Bioinformatics	Nov 05, 2018	This variant is interpreted as a Likely pathogenic for Deafness, autosomal recessive 32, with or without immotile sperm. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PP1-Strong : Segregation data PP1 upgraded to strong (PMID:29293958). -

For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg312 amino acid residue in CDC14A. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 29293958). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 expected to disrupt CDC14A protein function. ClinVar contains an entry for this variant (Variation ID: 559436). This missense change has been observed in individual(s) with deafness (PMID: 29293958). It has also been observed to segregate with disease in related individuals. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 312 of the CDC14A protein (p.Arg312Gly). -
