Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM2PP3_ModeratePP5_Very_Strong
The NM_000195.5(HPS1):c.716T>C(p.Leu239Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000193 in 1,556,306 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. L239L) has been classified as Likely benign.

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 30, 2024 | This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 239 of the HPS1 protein (p.Leu239Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Hermansky-Pudlak syndrome and/or ocular albinism (PMID: 12442288, 29345414). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. This variant is also known as c.922T>C. ClinVar contains an entry for this variant (Variation ID: 1452567). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HPS1 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. - |
