ClinVar
Submissions by phenotype
not provided Uncertain:1Benign:4
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

LOXHD1: BS2 -
Autosomal recessive nonsyndromic hearing loss 77 Uncertain:3Benign:1

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
not specified Uncertain:1Benign:3
p.Arg524Cys in exon 12 of LOXHD1: This variant is not expected to have clinical significance because it has been identified in 0.5% (44/8578) of Ashkenazi Jewis h chromosomes and 0.4% (291/73944) of European chromosomes including 1 homozygot e by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbS NP rs192376005}. This variant has also been reported in seven members of one fam ily with autosomal dominant, late onset Fuchs corneal dystrophy (FCD); however, one affected family member did not carry this variant and functional studies wer e not strongly supportive of pathogenicity (Riazzudin 2012). In summary, this va riant is benign based on its frequency in the general population and the evidenc e against an association with FCD, primarily the non-segregation. -

Variant summary: LOXHD1 c.1570C>T (p.Arg524Cys) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0027 in 160600 control chromosomes including one homozygote (gnomAD), predominantly at a frequency of 0.0044 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 4 fold of the estimated maximal expected allele frequency for a pathogenic variant in LOXHD1 causing Nonsyndromic Hearing Loss And Deafness, Type 77 phenotype (0.0011), suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.1570C>T has been reported in the literature in individuals affected with Nonsyndromic Hearing Loss And Deafness, Type 77 (Sheppard_2018), however this report does not provide unequivocal conclusions about association of the variant with Nonsyndromic Hearing Loss And Deafness, Type 77. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Eleven ClinVar submitters have assessed the variant since 2014: five have classified the variant as of uncertain significance, five as likely benign, and one as benign. Based on the evidence outlined above, the variant was classified as benign. -
LOXHD1-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
