Genes affected
ANO5 (HGNC:27337): (anoctamin 5) This gene encodes a member of the anoctamin family of transmembrane proteins. The encoded protein is likely a calcium activated chloride channel. Mutations in this gene have been associated with gnathodiaphyseal dysplasia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.55).
BS2
High AC in GnomAdExome4 at 66 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Uncertain significance, criteria provided, single submitterclinical testingInvitaeDec 04, 2023This sequence change falls in intron 20 of the ANO5 gene. It does not directly change the encoded amino acid sequence of the ANO5 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs199548403, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with ANO5-related conditions. ClinVar contains an entry for this variant (Variation ID: 288945). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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. -
