Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS1

The NM_153676.4(USH1C):​c.1906C>T​(p.Arg636Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000345 in 1,613,340 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R636H) has been classified as Likely benign.

Genes affected
USH1C (HGNC:12597): (USH1 protein network component harmonin) This gene encodes a scaffold protein that functions in the assembly of Usher protein complexes. The protein contains PDZ domains, a coiled-coil region with a bipartite nuclear localization signal and a PEST degradation sequence. Defects in this gene are the cause of Usher syndrome type 1C and non-syndromic sensorineural deafness autosomal recessive type 18. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0054422915).
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00124 (189/151918) while in subpopulation AFR AF = 0.00396 (164/41404). AF 95% confidence interval is 0.00347. There are 0 homozygotes in GnomAd4. There are 90 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position FAILED quality control check.

Arg636Cys in Exon 18 of USH1C: This variant has been reported in one individual with prelingual severe to profound deafness with no vision abnormalities (Ouyang 2002). However, this variant is not expected to have clinical significance beca use it has been identified in 0.5% (20/3738) of African American chromosomes fro m a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washin gton.edu/EVS; dbSNP rs149510892). In addition, this variant has been identified by our laboratory in a proband who carried two pathogenic variants in another ge ne. -
