Genes affected

STRC (HGNC:16035): (stereocilin) This gene encodes a protein that is associated with the hair bundle of the sensory hair cells in the inner ear. The hair bundle is composed of stiff microvilli called stereocilia and is involved with mechanoreception of sound waves. This gene is part of a tandem duplication on chromosome 15; the second copy is a pseudogene. Mutations in this gene cause autosomal recessive non-syndromic deafness. [provided by RefSeq, Jul 2008]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Ser1273Pro vari ant in STRC has not been previously reported in individuals with hearing loss, b ut has been identified in 1/4398 of African American chromosomes by the NHLBI Ex ome Sequencing Project (http://evs.gs.washington.edu/EVS; dbSNP rs144626173). Th e serine (Ser) at position 1273 is not conserved in mammals and evolutionarily d istant species, with many birds and reptiles having a proline (Pro) at this posi tion, suggesting that this change may be tolerated. Other computational tools d o not provide strong support for or against an impact to the protein. In summary , the clinical significance of this variant cannot be determined with certainty; however based upon the arguments described above, we would lean towards a more likely benign role.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3817T>C (p.S1273P) alteration is located in exon 19 (coding exon 19) of the STRC gene. This alteration results from a T to C substitution at nucleotide position 3817, causing the serine (S) at amino acid position 1273 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
