Intellectual disability v5.499 ZFHX3 Sarah Leigh edited their review of gene: ZFHX3: Added comment: Personal communication from Nour Elkhateeb (Clinical Fellow in Genomics, Genomics England): we have data about 12 individuals with nonsense/frameshift/exon deletions in ZFHX3. Five of the variants are located in exon 9/10 or exon 9, which has been shown to harbour the highest density of pathogenic variants (PMID: 38412861). Eleven of these cases presented with developmental delay / intellectual disability and a range of other features, including dysmorphology, seizures and failure to thrive.; Changed publications to: 38412861

PMID: 35614220 (2022) identified a homozygous nonsense variant (p.W25X) in a Turkish boy previously reported by PMID: 24194475 to have bilateral cleft lip, complete cleft palate, moderate to severe intellectual delay and dysmorphic features. FHx of cleft lip/cleft palate as well in relatives who were heterozygous for the reported variant

gene: FGF13 was marked as current diagnostic
Added comment: Two sibling pairs and three unrelated males reported who presented in infancy with intractable focal seizures and severe developmental delay. The variants were located in the N-terminal domain of the A isoform of FGF13/FHF2 (FHF2A). The X-linked FHF2 gene (also known as FGF13) has alternative first exons which produce multiple protein isoforms that differ in their N-terminal sequence. The variants were located at highly conserved residues in the FHF2A inactivation particle that competes with the intrinsic fast inactivation mechanism of Nav channels. Functional characterization of mutant FHF2A co-expressed with wild-type Nav1.6 (SCN8A) revealed that mutant FHF2A proteins lost the ability to induce rapid-onset, long-term blockade of the channel while retaining pro-excitatory properties. These gain-of-function effects are likely to increase neuronal excitability consistent with the epileptic potential of FHF2 variants.
