Genes affected

NHS (HGNC:7820): (NHS actin remodeling regulator) This gene encodes a protein containing four conserved nuclear localization signals. The encoded protein functions in eye, tooth, craniofacial and brain development, and it can regulate actin remodeling and cell morphology. Mutations in this gene have been shown to cause Nance-Horan syndrome, and also X-linked cataract-40. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, May 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.89).

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00697 (780/111847) while in subpopulation SAS AF = 0.0247 (66/2676). AF 95% confidence interval is 0.0199. There are 6 homozygotes in GnomAd4. There are 226 alleles in the male GnomAd4 subpopulation. Median coverage is 22. This position passed quality control check.

BS2

High AC in GnomAd4 at 780 XL,AD gene.
