Variant summary
Our verdict is Benign. Variant got -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2
The NM_000075.4(CDK4):c.776C>T(p.Ser259Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000128 in 1,614,006 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S259P) has been classified as Uncertain significance.

Likely benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Mar 05, 2024 | Variant summary: HSD3B2 c.776C>T (p.Thr259Met) results in a non-conservative amino acid change located in the 3-beta hydroxysteroid dehydrogenase/isomerase domain (IPR002225) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 251122 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.776C>T has been reported in the literature in multiple homozygous and compound heterozygous individuals affected with Congenital Adrenal Hyperplasia (e.g., Lutfallah_2002, Marui_2000, Moisan_1999, Zhang_1999). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function, finding that the variant resulted in <10% of normal enzymatic activity in COS-1 cells (e.g., Zhang_1999). The following publications have been ascertained in the context of this evaluation (PMID: 12050224, 10973654, 10599696, 10770215). ClinVar contains an entry for this variant (Variation ID: 12192). Based on the evidence outlined above, the variant was classified as pathogenic. - |
