Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 1P and 1B. PP2 BP4

The NM_001037582.3(SCD5):​c.732G>A​(p.Met244Ile) variant causes a missense change. The variant allele was found at a frequency of 0.0000116 in 1,461,890 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M244T) has been classified as Uncertain significance.

Genes affected

SCD5 (HGNC:21088): (stearoyl-CoA desaturase 5) Stearoyl-CoA desaturase (SCD; EC 1.14.99.5) is an integral membrane protein of the endoplasmic reticulum that catalyzes the formation of monounsaturated fatty acids from saturated fatty acids. SCD may be a key regulator of energy metabolism with a role in obesity and dislipidemia. Four SCD isoforms, Scd1 through Scd4, have been identified in mouse. In contrast, only 2 SCD isoforms, SCD1 (MIM 604031) and SCD5, have been identified in human. SCD1 shares about 85% amino acid identity with all 4 mouse SCD isoforms, as well as with rat Scd1 and Scd2. In contrast, SCD5 shares limited homology with the rodent SCDs and appears to be unique to primates (Wang et al., 2005 [PubMed 15907797]).[supplied by OMIM, Mar 2008]

SCD5 Gene-Disease associations (from GenCC):

• hearing loss, autosomal dominant 79

  Inheritance: AD, Unknown Classification: LIMITED Submitted by: PanelApp Australia, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.91657 (below the threshold of 3.09). Trascript score misZ: 1.4213 (below the threshold of 3.09). GenCC associations: The gene is linked to hearing loss, autosomal dominant 79.
• BP4: Computational evidence support a benign effect (MetaRNN=0.38792875).
