Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 1P and 12B. PP2BP4_StrongBS1BS2

The NM_017541.4(CRYGS):c.355A>G(p.Met119Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000242 in 1,614,100 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M119L) has been classified as Uncertain significance.

Genes affected

CRYGS (HGNC:2417): (crystallin gamma S) Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins. Mammalian lens crystallins are divided into alpha, beta, and gamma families; beta and gamma crystallins are also considered as a superfamily. Alpha and beta families are further divided into acidic and basic groups. Seven protein regions exist in crystallins: four homologous motifs, a connecting peptide, and N- and C-terminal extensions. Gamma-crystallins are a homogeneous group of highly symmetrical, monomeric proteins typically lacking connecting peptides and terminal extensions. They are differentially regulated after early development. This gene encodes a protein initially considered to be a beta-crystallin but the encoded protein is monomeric and has greater sequence similarity to other gamma-crystallins. This gene encodes the most significant gamma-crystallin in adult eye lens tissue. Whether due to aging or mutations in specific genes, gamma-crystallins have been involved in cataract formation.

ACMG classification

Classification was made for transcript

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

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 0.2428 (below the threshold of 3.09). Trascript score misZ: 0.85394 (below the threshold of 3.09). GenCC associations: The gene is linked to cataract 20 multiple types, early-onset lamellar cataract, early-onset sutural cataract.

BP4

Computational evidence support a benign effect (MetaRNN=0.02276513).

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000105 (16/152240) while in subpopulation AFR AF = 0.000337 (14/41524). AF 95% confidence interval is 0.000204. There are 0 homozygotes in GnomAd4. There are 10 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 16 AD gene.
