Genes affected

PAM16 (HGNC:29679): (presequence translocase associated motor 16) This gene encodes a mitochondrial protein involved in granulocyte-macrophage colony-stimulating factor (GM-CSF) signaling. This protein also plays a role in the import of nuclear-encoded mitochondrial proteins into the mitochondrial matrix and may be important in reactive oxygen species (ROS) homeostasis. Mutations in this gene cause Megarbane-Dagher-Melike type spondylometaphyseal dysplasia, an early lethal skeletal dysplasia characterized by short stature, developmental delay and other skeletal abnormalities. [provided by RefSeq, May 2017]

PAM16 links:

CORO7-PAM16 (HGNC:44424): (CORO7-PAM16 readthrough) This locus represents naturally occurring read-through transcription between the neighboring CORO7 (coronin 7) and PAM16 (presequence translocase-associated motor 16) genes on chromosome 16. The read-through transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jan 2011]

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 100 of the PAM16 protein (p.Arg100His). This variant is present in population databases (rs775983589, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with PAM16-related conditions. ClinVar contains an entry for this variant (Variation ID: 1494383). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
