Genes affected

AQP7 (HGNC:640): (aquaporin 7) This gene encodes a member of the aquaporin family of water-selective membrane channels. The encoded protein localizes to the plasma membrane and allows movement of water, glycerol and urea across cell membranes. This gene is highly expressed in the adipose tissue where the encoded protein facilitates efflux of glycerol. In the proximal straight tubules of kidney, the encoded protein is localized to the apical membrane and prevents excretion of glycerol into urine. The encoded protein is present in spermatids, as well as in the testicular and epididymal spermatozoa suggesting an important role in late spermatogenesis. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. This gene is located adjacent to a related aquaporin gene on chromosome 9. Multiple pseudogenes of this gene have been identified. [provided by RefSeq, Dec 2015]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 6: AlphaMissense, BayesDel_noAF, Cadd, Eigen, phyloP100way_vertebrate, PROVEAN [when BayesDel_addAF, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.008925259).

BA1

GnomAdExome4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.0524 is higher than 0.05.
