Variant summary
Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM2PM5PP3_ModeratePP5_Very_Strong
The NM_031372.4(HNRNPDL):c.1132G>C(p.Asp378His) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D378N) has been classified as Likely pathogenic.

Genes affected
HNRNPDL (HGNC:5037): (heterogeneous nuclear ribonucleoprotein D like) This gene belongs to the subfamily of ubiquitously expressed heterogeneous nuclear ribonucleoproteins (hnRNPs). The hnRNPs are RNA binding proteins and they complex with heterogeneous nuclear RNA (hnRNA). These proteins are associated with pre-mRNAs in the nucleus and appear to influence pre-mRNA processing and other aspects of mRNA metabolism and transport. While all of the hnRNPs are present in the nucleus, some seem to shuttle between the nucleus and the cytoplasm. The hnRNP proteins have distinct nucleic acid binding properties. The protein encoded by this gene has two RRM domains that bind to RNAs. Three alternatively spliced transcript variants have been described for this gene. One of the variants is probably not translated because the transcript is a candidate for nonsense-mediated mRNA decay. The protein isoforms encoded by this gene are similar to its family member HNRPD. [provided by RefSeq, May 2011]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 05, 2024 | This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 378 of the HNRNPDL protein (p.Asp378His). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with autosomal dominant limb-girdle muscular dystrophy (PMID: 24647604). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 144074). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. - |
