Genes affected

TMEM147 (HGNC:30414): (transmembrane protein 147) Enables ribosome binding activity. Located in endoplasmic reticulum membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PS1: Transcript NM_032635.4 (TMEM147) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a chain BOS complex subunit TMEM147 (size 223) in uniprot entity TM147_HUMAN there are 9 pathogenic changes around while only 1 benign (90%) in NM_032635.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.935
• PP5: Variant 19-35546998-T-A is Pathogenic according to our data. Variant chr19-35546998-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 1708022.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr19-35546998-T-A is described in Lovd as [Pathogenic].
