Genes affected

LDHAL6B (HGNC:21481): (lactate dehydrogenase A like 6B) Predicted to enable L-lactate dehydrogenase activity. Predicted to be involved in pyruvate metabolic process. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

LDHAL6B links:

MYO1E (HGNC:7599): (myosin IE) This gene encodes a member of the nonmuscle class I myosins which are a subgroup of the unconventional myosin protein family. The unconventional myosin proteins function as actin-based molecular motors. Class I myosins are characterized by a head (motor) domain, a regulatory domain and a either a short or long tail domain. Among the class I myosins, this protein is distinguished by a long tail domain that is involved in crosslinking actin filaments. This protein localizes to the cytoplasm and may be involved in intracellular movement and membrane trafficking. Mutations in this gene are the cause of focal segmental glomerulosclerosis-6. This gene has been referred to as myosin IC in the literature but is distinct from the myosin IC gene located on chromosome 17. [provided by RefSeq, Jan 2012]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.06908631).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000342 (50/1461862) while in subpopulation NFE AF= 0.0000432 (48/1111986). AF 95% confidence interval is 0.0000334. There are 0 homozygotes in gnomad4_exome. There are 23 alleles in male gnomad4_exome subpopulation. Median coverage is 57. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.134C>T (p.T45I) alteration is located in exon 1 (coding exon 1) of the LDHAL6B gene. This alteration results from a C to T substitution at nucleotide position 134, causing the threonine (T) at amino acid position 45 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
