Genes affected

CACNA1F (HGNC:1393): (calcium voltage-gated channel subunit alpha1 F) This gene encodes a multipass transmembrane protein that functions as an alpha-1 subunit of the voltage-dependent calcium channel, which mediates the influx of calcium ions into the cell. The encoded protein forms a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. Mutations in this gene can cause X-linked eye disorders, including congenital stationary night blindness type 2A, cone-rod dystropy, and Aland Island eye disease. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Aug 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011872292).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00227 (252/110916) while in subpopulation NFE AF= 0.00405 (214/52878). AF 95% confidence interval is 0.0036. There are 0 homozygotes in gnomad4. There are 63 alleles in male gnomad4 subpopulation. Median coverage is 21. This position pass quality control queck.

BS2
