Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_017433.5(MYO3A):c.3859C>A(p.Pro1287Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0107 in 1,614,124 control chromosomes in the GnomAD database, including 118 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 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. P1287R) has been classified as Uncertain significance.

Genes affected

MYO3A (HGNC:7601): (myosin IIIA) The protein encoded by this gene belongs to the myosin superfamily. Myosins are actin-dependent motor proteins and are categorized into conventional myosins (class II) and unconventional myosins (classes I and III through XV) based on their variable C-terminal cargo-binding domains. Class III myosins, such as this one, have a kinase domain N-terminal to the conserved N-terminal motor domains and are expressed in photoreceptors. The protein encoded by this gene plays an important role in hearing in humans. Three different recessive, loss of function mutations in the encoded protein have been shown to cause nonsyndromic progressive hearing loss. Expression of this gene is highly restricted, with the strongest expression in retina and cochlea. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0032796562).

BP6

Variant 10-26174123-C-A is Benign according to our data. Variant chr10-26174123-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 45810.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00814 (1240/152246) while in subpopulation NFE AF = 0.0115 (783/68012). AF 95% confidence interval is 0.0108. There are 8 homozygotes in GnomAd4. There are 615 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 8 AR,SD,AD gene
