Gastrointestinal neuromuscular disorders
Gene: FLNA
Comment on list classification: Gene rated green and diagnostic by reviewer. 2 family reports and unrelated singleton in OMIM - these cases all include a 2-bp deletion in exon 2 (6_17delTC rs398122521 and rs80338840 65-66delAC have been reported). Further cases found in literature search PMID: 26059841 - a 4bp deletion in exon 40 identified in two siblings who had atypical clinical courses, such as a lack of PVNH and a spontaneous improvement of CIPO, and PMID: 20871226. PMID: 18854860 - duplications of several genes in the region. Overall, more than 3 family reports.Created: 19 Oct 2016, 10:12 a.m.
Mode of inheritance
X-LINKED: hemizygous mutation in males, biallelic mutations in females
Variants in this GENE are reported as part of current diagnostic practice
Phenotypes for gene: FLNA were changed from Intestinal pseudoobstruction, neuronal 300048; Congenital short bowel syndrome 300048 to Congenital short bowel syndrome, OMIM:300048; Intestinal pseudoobstruction, neuronal, OMIM:300048
26th October 2016: panel revised after expert review and further curation of the analysis, with then internal clinical review. Ready for promotion to version 1.
This gene has been classified as Green List (High Evidence).
Publications for FLNA were set to 17357080; 23037936; 26059841 - the two siblings who had atypical clinical courses, such as a lack of PVNH and a spontaneous improvement of CIPO. A 4-bp deletion in exon 40 was reported, and functional studies revealed that the variant induced in-frame skipping of the mutated exon, which led to the translation of a mutant FLNA missing an internal region of 41 amino acids. "Functional analyses of the mutant protein suggested that its binding affinity to integrin, as well as its capacity to induce focal adhesions, were comparable to those of the wild-type protein. These results suggested that exon skipping of FLNA partially restored its protein function, which could contribute to amelioration of the siblings' clinical courses."; 20871226; 18854860
