Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_001378454.1(ALMS1):c.11407C>T(p.Pro3803Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000168 in 1,614,072 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. P3803R) has been classified as Uncertain significance.

Genes affected

ALMS1 (HGNC:428): (ALMS1 centrosome and basal body associated protein) This gene encodes a protein containing a large tandem-repeat domain as well as additional low complexity regions. The encoded protein functions in microtubule organization, particularly in the formation and maintanance of cilia. Mutations in this gene cause Alstrom syndrome. There is a pseudogene for this gene located adjacent in the same region of chromosome 2. Alternative splice variants have been described but their full length nature has not been determined.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.019027323).

BP6

Variant 2-73573284-C-T is Benign according to our data. Variant chr2-73573284-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 412661.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000847 (129/152260) while in subpopulation AFR AF = 0.00284 (118/41556). AF 95% confidence interval is 0.00242. There are 0 homozygotes in GnomAd4. There are 62 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
