Genetic Variant NM_001291867.2:c.310_345dupCCCGCAGCCGGCGAGGCGTCCTCGGCGGCGGCGGCG (chrX-17376059-A-AGGCGGCGCCCGCAGCCGGCGAGGCGTCCTCGGCGGC) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP3

The NM_001291867.2(NHS):c.310_345dupCCCGCAGCCGGCGAGGCGTCCTCGGCGGCGGCGGCG(p.Pro104_Ala115dup) variant causes a conservative inframe insertion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000904 in 110,643 control chromosomes in the GnomAD database, with no homozygous occurrence. There are no hemizygote samples in GnomAD. It is difficult to determine the true allele frequency of this variant because it is of type INS_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]
