Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM1PM2PP3_Moderate
The NM_000260.4(MYO7A):āc.758A>Gā(p.His253Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000072 in 1,611,582 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. H253H) has been classified as Uncertain significance.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Apr 04, 2014 | The His253Arg variant in MYO7A has not been previously reported in individuals w ith hearing loss, but has been identified in 0.05% (2/3912) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/). Although this variant has been seen in the general population, its freque ncy is not high enough to rule out pathogenicity. Computational prediction tools and conservation analyses do not provide strong support for or against an impac t to the protein. In summary, additional information is needed to determine the clinical significance of this variant. - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 14, 2021 | The c.758A>G (p.H253R) alteration is located in exon 8 (coding exon 7) of the MYO7A gene. This alteration results from a A to G substitution at nucleotide position 758, causing the histidine (H) at amino acid position 253 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
