Is ASPM p.Leu2195Phe (c.6583C>T) pathogenic?

ASPM p.Leu2195Phe (c.6583C>T) is classified Uncertain significance in ASPM (ClinVar, Multiple submitters, 3 submitters; last evaluated 2025-05-15). AlphaMissense: likely benign (0.1229); Very rare (popmax 0.00432%, nfe); Associated with Inborn genetic diseases.

What condition is associated with ASPM p.Leu2195Phe (c.6583C>T)?

ASPM p.Leu2195Phe (c.6583C>T) is associated with Inborn genetic diseases, microcephaly 5, primary, autosomal recessive (ClinVar).

How common is ASPM p.Leu2195Phe (c.6583C>T) in the general population?

ASPM p.Leu2195Phe (c.6583C>T) is very rare (popmax 0.00432%, nfe) (gnomAD).

What do computational predictors say about ASPM p.Leu2195Phe (c.6583C>T)?

AlphaMissense predicts likely benign (score 0.1229) — an in-silico prediction, not a clinical call.

Computational evidence

Protein change
AlphaMissense	0.1229	likely benign
REVEL	0.159	moderately benign-leaning
⇒ AlphaMissense and REVEL both call this tolerated.

Overall
CADD	17.03	PHRED · no single calibrated threshold — expert panels disagree

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
