Genes affected

ENSG00000248968 (HGNC:):

ATPSCKMT (HGNC:27029): (ATP synthase c subunit lysine N-methyltransferase) Enables protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine trimethylation; positive regulation of sensory perception of pain; and regulation of proton transport. Located in mitochondrial crista. [provided by Alliance of Genome Resources, Apr 2022]

CCT5 (HGNC:1618): (chaperonin containing TCP1 subunit 5) The protein encoded by this gene is a molecular chaperone that is a member of the chaperonin containing TCP1 complex (CCT), also known as the TCP1 ring complex (TRiC). This complex consists of two identical stacked rings, each containing eight different proteins. Unfolded polypeptides enter the central cavity of the complex and are folded in an ATP-dependent manner. The complex folds various proteins, including actin and tubulin. Mutations in this gene cause hereditary sensory and autonomic neuropathy with spastic paraplegia (HSNSP). Alternative splicing results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 5 and 13. [provided by RefSeq, Apr 2015]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
