RCV001261013 | SCV001438400 | likely pathogenic | Nonsyndromic genetic hearing loss | 2020-10-20 | reviewed by expert panel | curation | The c.1183C>T (p.Arg395Cys) variant in MYO7A was identified in 0.0085% (2/23608) of South Asian alleles in gnomAD v2 (PM2_Supporting). This variant has been detected in 2 patients with hearing loss. One patient had profound prelingual sensorineural hearing loss while the other had progressive severe hearing loss. For both of these probands the variant was observed in a homozygous state (PM3_Supporting, PMIDs: 23770805, 27573290). The variant has been reported to segregate with disease in at least 3 affected family members (PP1_Strong, PMID: 23770805). The REVEL computational prediction tool produced a score of 0.773, which is above the threshold necessary to apply PP3. In summary, this variant meets criteria to be classified as likely pathogenic for autosomal recessive hearing loss. There was not sufficient evidence to determine if this variant is causative for Usher syndrome or nonsyndromic hearing loss. ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel: PP1_Strong, PM2_Supporting, PM3_Supporting, PP3. |

Invitae | RCV001067075 | SCV001232108 | pathogenic | not provided | 2022-09-27 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MYO7A protein function. ClinVar contains an entry for this variant (Variation ID: 555138). This missense change has been observed in individual(s) with autosomal recessive hearing loss (PMID: 23770805, 27573290). It has also been observed to segregate with disease in related individuals. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 395 of the MYO7A protein (p.Arg395Cys). |
