Genes affected
ATP6V1F (HGNC:16832): (ATPase H+ transporting V1 subunit F) This gene encodes a component of vacuolar ATPase (V-ATPase), a multisubunit enzyme that mediates acidification of eukaryotic intracellular organelles. V-ATPase dependent organelle acidification is necessary for such intracellular processes as protein sorting, zymogen activation, receptor-mediated endocytosis, and synaptic vesicle proton gradient generation. V-ATPase is composed of a cytosolic V1 domain and a transmembrane V0 domain. The V1 domain consists of three A and three B subunits, two G subunits plus the C, D, E, F, and H subunits. The V1 domain contains the ATP catalytic site. The V0 domain consists of five different subunits: a, c, c', c", and d. Additional isoforms of many of the V1 and V0 subunit proteins are encoded by multiple genes or alternatively spliced transcript variants. This encoded protein is the V1 domain F subunit protein.

KCP (HGNC:17585): (kielin cysteine rich BMP regulator) Predicted to act upstream of or within hematopoietic progenitor cell differentiation and positive regulation of BMP signaling pathway. Predicted to be located in extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

The c.245A>T (p.Q82L) alteration is located in exon 3 (coding exon 3) of the ATP6V1F gene. This alteration results from a A to T substitution at nucleotide position 245, causing the glutamine (Q) at amino acid position 82 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
