Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 1P and 6B. PP3BP6_ModerateBS2

The NM_006918.5(SC5D):c.16C>T(p.Arg6Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000224 in 1,613,766 control chromosomes in the GnomAD database, including 4 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R6P) has been classified as Uncertain significance.

Genes affected

SC5D (HGNC:10547): (sterol-C5-desaturase) This gene encodes an enzyme of cholesterol biosynthesis. The encoded protein catalyzes the conversion of lathosterol into 7-dehydrocholesterol. Mutations in this gene have been associated with lathosterolosis. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]
