Genes affected

CRYM (HGNC:2418): (crystallin mu) Crystallins are separated into two classes: taxon-specific and ubiquitous. The former class is also called phylogenetically-restricted crystallins. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. This gene encodes a taxon-specific crystallin protein that binds NADPH and has sequence similarity to bacterial ornithine cyclodeaminases. The encoded protein does not perform a structural role in lens tissue, and instead it binds thyroid hormone for possible regulatory or developmental roles. Mutations in this gene have been associated with autosomal dominant non-syndromic deafness. [provided by RefSeq, Sep 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.012759268).

BP6

Variant 16-21275576-T-C is Benign according to our data. Variant chr16-21275576-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 179476.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.00108 (1585/1461748) while in subpopulation SAS AF = 0.0173 (1493/86244). AF 95% confidence interval is 0.0166. There are 28 homozygotes in GnomAdExome4. There are 1151 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.

BS2

High AC in GnomAd4 at 90 AD,Unknown gene.
