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]
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]

The c.230C>G (p.T77S) alteration is located in exon 1 (coding exon 1) of the LDHAL6B gene. This alteration results from a C to G substitution at nucleotide position 230, causing the threonine (T) at amino acid position 77 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
